...Hormones and Behavior Shaquanna L. Miley BEH /225 02/ 26/2015 Pamela Applewhite The Endocrine system is the collection of glands that produce hormones that regulate metabolism, growth and development, tissue, function, reproduction, sleep, and mood (Livescience 2015). The Endocrine system plays a big role with the production of hormones. Hormones can affect a person’s behavior and mood tremendously. Hormones are chemical messengers that are secreted directly into the blood. The Endocrine system is made up of a couple of endocrine glands such as the thyroid gland, the pineal gland the adrenal gland and the pituitary gland. Each of these glands secretes different hormones, and all these hormones have a different effect on the body’s behavior. The Thyroid gland location is in the neck and secretes thyroxin, Triiodothyronine, and calcitonin from this gland metabolism is controlled. The thyroid gland secretes three hormones the thyroid gland also produces T3 and T4 hormones. T3 and T4 hormones regulate the growth and rate of many functions within the body. Thyroids are essential for the function of the cells within the body. The thyroid gland also helps children grow and develop. The pineal gland location is between the two cerebral hemispheres of the brain and secretes the hormone melatonin. The melatonin hormone helps regulate sleep and wake cycles. Melatonin production is high in infancy and declines with age. Melatonin has also been used...

...Hormones and Behavior Lindsey Hensley University of Phoenix June 9, 2013 Nancy Russell BEH/225 Hormones are materials in the human body that impact emotional and physical behavior. They are formed by the glands in the endocrine system. When needed, they are discharged into the bloodstream, which then gets to the cells of the imperative tissue and the cells react to it. The correlation between hormones and behavior is bi-directional, suggesting that hormones can change behavior, but the way we operate can also release hormones. Consequently, hormones are also often called biological carriers. The response to a hormone may not always be prompt, but every hormone does affect the human body in either or short or long terms if released. Two hormones that are being addressed in this essay are: Oxytocin and Melatonin, which both change the human behavior. In the hypothalamus the hormone oxytocin is produced. It is released directly into the bloodstream via the pituitary gland, or to others parts of the brain and spinal cord. The pituitary glands main function is to stimulate growth. Oxytocin is another important hormone released from the pituitary gland. Oxytocin is often termed the “love/trust hormone.” It is known to raise feelings of happiness. (Coon & Mitterer) It was first recognized in the 1990s, researchers realized that it was released during breastfeeding which caused certain emotional feelings in women. It was established that Oxytocin was consistent to sociable...

...Checkpoint: Hormones and Behavior Checkpoint: Hormones and Behavior The brain is a very complex organ that controls everything we do. The central nervous system and spinal cord play a huge role in our behavior. Hormones affect behavior when we get anxious, excited, or even depressed. Hormones are chemical messengers secreted by cell or gland (Cherry, 2012). The term hormone was introduced by Bayliss and Starling in 1902 to describe a chemical substance that travels around the body influencing physiology and behavior (Gibson, 2010). Hormones tell the body to execute certain physical and intellectual behaviors’. The system that is responsible for producing hormones is called, “The endocrine system”. The endocrine system is made up of glands that secrete chemicals directly into the bloodstream or lymph system (Coon/Mitterer, 2011). The effects of hormones are different for men and women. Women produce hormones called, “estrogen”. This hormone affects a woman’s moods and emotions. Another hormone that can affect both men and women are called, “Steroids”. When the steroid passes into the bloodstream to the brain; this causes changes in behavior. The steroid hormone can cause anger and aggressive behavior in both men and women. There are eight different glands that all have different objectives. One gland is the “thyroid” which regulates a person’s metabolic rate, which is the amount of energy expended daily by a person at rest ("The Endocrine System", 2010). The thyroid gland...

...Hormones and Behaviors Tiffany Stevens April 17, 2015 BEH/225 Krystyn A. Lassiter Hormones and Behaviors The endocrine system is made up of glands that release hormones into the blood stream. There are several types of hormones released by these various glands in the body, each doing a different job. Hormones are similar to neurotransmitters. Transmitters of Couse are responsible for moving information to the cells in the body. These communications cause cells in the body to become active. Hormones affect everything from puberty to jet lag even personality. Hormones can even have an effect on mood and behavior. An example of this would be oxytocin. Oxytocin is a hormone produced and released by the pituitary gland. The pituitary gland is often referred to as the master gland because it affects other glands in the endocrine system. Oxytocin is a hormone mostly responsible for its effects on mood and causing happiness. The more oxytocin produced in the body, the happier an individual will feel. A lack of production of oxytocin in the system may cause an individual to feel moods such as sadness or depression. The pituitary gland is also responsible for growth in humans by producing growth hormones. Another hormone responsible for behavior in people is the hormone melatonin. Melatonin controls sleep behaviors in individuals. The pineal gland produces melatonin. Depending on the changes in light the pineal gland will produce the appropriate levels of melatonin. The production...

...Hormones, Behavior, and Gender Identity Psy 340 Hormones, Behavior, and Gender Identity Often enough, parents of an unburned child are eagerly excited to find out the sex of the couple’s child to enable planning such as a fitted name, nursery décor, and every extra-curricular and career aspirations. It is from that point forward nature and nurture work together hand in hand to create the child into society’s ideal male or female. Different changes occur, such as biologically, psychologically, and emotionally, depending of the gender of the baby; however, social situations and upbringing will not only be exposed according to the sex, but also the individual child. Certain times, the gender and the sex of an individual do not coordinate with one another. This uncertainty has caused and is currently causing misunderstandings to numerous psychologists, neuroscientists and parents. The origin of the development of gender begins at conception, and the point creates a separation between the male and female gender roles. This paper will discuss interactions between hormones and behaviors, as well as, how the interactions affect the determination of gender identity. Biological psychology takes into consideration the gender from different perspectives of the functions coming from different sexual organs and the underlying physiology (Wickens, 2005). Biological and environmental factor will also be explored, as well as, the influence of nature versus nurture in an individual’s...

...Towner PSYC 340 07/29/13 The effects of Hormones and behavior on gender identity Gender development begins when a baby is conceived, which why most women want to know the sex of their child as soon as possible. Boys and girl are treated different from the day they are born, causing the environment- nurture to affect gender development. Although nurture has a major influence on gender development, biological factors-nature also play a major part in the effects of gender development. In this paper the discussion that will address is the interaction between hormones and behavior and how they affect gender identity, also how the argument of how nature and nurture is the main affect gender identity. Biological factors play a huge role in children’s growth development. For example, boys and girls develop with a significantly different sex organs, and they also become more different when the onset of puberty sets in. Puberty is when the chemical messenger called hormones start to help with the formation of appearance from the physical changes occurring inside the body of an adolescent. According to Oswalt & Dombeck (2013), some researchers introduced the thought of same sex hormones that make sex organs differentiation in the uterus, which later triggers puberty. Naturally, human bodies go through the stage of puberty, and hormones have a lot to do with the development of the individual body during the onset of puberty. Hormones are leading players in the body’s chemistry...

...Human behavior can be affected by several factors; a person’s upbringing, the surrounding environment, and one’s personality. These are all examples of what one sees on the outside of the body. Inside the body, there is a system that can have several effects on human behavior. This system is called the endocrine system. This system is made up of glands that secrete hormones into the lymph system, also known as the bloodstream. Glands such as the thyroid and adrenal secrete hormones that affect human behavior. The thyroid gland secretes thyroid hormones such as triiodothyronine (T3) and thyroxine (T4), which regulate the human body’s metabolism. The adrenal glands secrete hormones such as, adrenalin and noradrenalin which can be related to fear and anger. The endocrine system’s secretions of hormones throughout the human body plays a large role on how a human behavior. The Role of the Endocrine System Like the nervous system, the endocrine system goes hand-in-hand in controlling and coordinating the reflexes and reactions of the human body. The endocrine glands create and execute communications throughout the body that are just as important as the nervous system (Coon & Mitterer, p. 74, 2012). Through secretion of chemicals, also known as hormones, the endocrine system secretes these hormones into the human bloodstream. Depending on which hormone is secreted into the bloodstream, can have a large effect on human behavior. There are many hormones that...

...Heredity and Hormones BEH/225 February 6, 2013 L Heredity and Hormones Heredity and hormones work jointly to influence behavior. They both influence human behavior but from very different aspects. Heredity is qualities, traits, and characteristics passed from generation to generation through genes. Whether a person has blue or brown eyes tall or short these are things passed on through heredity, however it is not just the physical attributes that can be inherited from generation to generation, intelligence and personality traits and behavior can be inherited also. The nature vs nurture plays a role in heredity as well because even though some behavior is inherited environmental factors can have a major influence on human behavior. The environment can mold human behavior and can also reinforce heredity which contributes to behavior. The heredity aspect of human behavior is so delicate and complex that is more difficult to understand or describe. Hormones approach on the influence of human behavior is not as subtle as heredity. Hormonal changes can cause physical changes especially in stages of adolescents for girls in boys. Hormones can cause changes in men and women. Hormonal changes can also cause certain behaviors to occur such as depression and aggression and a series of other things that can be responsible for causing psychological disorders. Hormones make it easier to measure the influences it has on behavior then heredity is. The endocrine system plays a major...

It helps coordinate and integrate complex psychological reactions the endocrine system, it also works with the nervous system because together they are constantly transferring chemicals to each other. The endocrine system has five glands and they all produce hormones for different things, they produce hormones and they spread through the bloodstream. We have a thyroid gland that produces thyroxin, which is a primary hormone that helps regulate the body’s metabolism. We also have a pineal gland, which creates the hormone melatonin, and this hormone helps with sleep-wake cycles. The parathyroids are four tiny organs that control balance. The pancreas controls the level of sugar in the blood this is controlled by two hormones: insulin and glucagon. The gland that produces the most hormones is the pituitary gland the hormones controls high blood pressure, thirst, sexual behavior and other body functions. The pituitary gland is the master gland because it affects other glands. Our endocrine system has a gland that produces hormones and if the hormones are not produced correctly it affects the behavior with our body. Other things affect us on in human behavior. We have two things that influences or affects the heredity on human behavior, which are behavior genetics and evolutionary psychology. The difference...

...Gender Identity Paper Ashley Spinner Monday, July 02, 2012 PSY/340 Manon Doll Gender Identity Paper The human body is interconnected to two very different superhighway systems. These systems are the nervous system and the endocrine system. The endocrine system is responsible for secreting chemical messengers called hormones. According to (Myers, 2008, p 45),“hormones are chemical messengers, manufactured by the endocrine glands, which are produced in one tissue and affect another.” Hormones travel through the body in the bloodstream. The human body is comprised of two very important informational highways that influence every bit of aggression, food, and sexual desire that the brain process. The nervous system and the endocrine system are relatives; therefore both systems secrete molecules that activate receptors in a different place. The interaction between hormones and behavior is quite complex. The body reacts to different levels of many hormones that are needed for the daily networking of the body and its functions. The hormones in the endocrine system control many aspects of an individual’s life. Some of those aspects are growth, reproduction, metabolism, moods. The body tries to hold everything in check while maintaining a balancing act among dealing with stress, the human thought pattern, and human actions. These actions take place in the sympathetic nervous system, which controls arousal. This section of the human spinal cord operates in many ways. It dilates the...

...of heredity on human behavior. Behavior genetics focuses on the extent to which heredity accounts for individual differences in behavior and thinking. Evolutionary psychology studies the evolutionary roots of behaviors and mental processes that all human beings share. Behavior geneticists study the topics that interest all psychologists perception, learning and memory, motivation and emotions, personality, and psychological disorders but from a genetic perspective. Their goal is to identify what genes contribute to intelligence, temperament, talents, and other characteristics, as well as genetic predispositions to psychological and neurological disorder. Evolutionary psychologists study the origins of behaviors and mental processes, emphasizing the adaptive or survival value of such traits. Evolutionary psychologists look at the role that natural selection might have played in selecting for adaptive behaviors, especially during the long period that our ancestors lived as hunter gatherers. The nervous system is not the only mechanism that regulates the functioning of our bodies. The endocrine system plays a key role in helping to coordinate and integrate complex psychological reactions. In fact, as we’ve noted throughout this chapter, the nervous system and the endocrine system work together in a constant chemical conversation. The endocrine glands release chemical substances called hormones that are carried throughout your body by the bloodstream. Hormones serve a similar function...

...and Hormones BEH/225 3/7/2013 David Stephensen Axia College of University of Phoenix The behavior of humans change depending on each individual as each person is different. The tendencies of committing a crime, or be more intelligent or very aggressive are signs of human behavior. In biological terms these are the outcome of behavior are as a result of hormones and genes. Heredity is the foundation upon which human behavior is built. Human behavior can be influenced by genes that are already present in the framework of the person. Genes are inherited when they are passed down from parent to child. The environment can cause our genes to change, or mutate. The way that heredity influences behavior over time may change and it may not always have an influence in the future. The endocrine system is a system of glands where each gland has a type of hormone that secretes directly into the bloodstream. Hormones are chemical substances released into the bloodstream through the endocrine glands and serve a similar function or purpose to the neurotransmitters.

...Checkpoint: Heredity and Hormones Elizabeth L. Saylor BEH 225 November 3, 2011 Axia University of Phoenix Checkpoint: Heredity and Hormones Heredity and hormones can make or break a person. To compare and contrast the influence of heredity and hormones on human behavior we must first understand what each is and what role it plays. Hormones are chemical substance that is released into the bloodstream to guide the processes of sexual development, metabolism, and growth (Morris & Maisto, 2005). Hormones have different effects on the different genders. With women hormones cause mood swings, people always assume that when a female in menstruating she is automatically in a bad mood that is not the case what happens are the women’s hormones are out of balance and this causes the “mood swings”. Thank goodness there are medications both over the counter and Doctor prescribed to help balance out the hormones. Hormones organize the entire nervous system during puberty. Hormones are responsible for behaviors because they affect alertness, excitability, sexual behavior, concentration, aggressiveness, and how one reacts to stress (Morris & Maisto, 2005). The hormones estrogen and androgen cause acne flare-ups when they are out of balance. The endocrine glands are the main glands that regulate our hormones. Endocrine glands are pituitary gland, gonads, thyroid gland, and the pineal gland (Morris & Maisto, 2005). Heredity is when genes and personal traits are passed...

...Heredity and Hormones Elizabeth Priest The way that we as human beings, behave and react to situations is shaped by many factors, heredity and hormones being the most prominent. Heredity is the foundation upon which human behavior is built. Human behavior can be influenced by genes that are already present in the framework of the person. Genes are inherited when they are passed down from parent to child. The environment can cause our genes to change, or mutate. The way that heredity influences behavior over time may change and it may not always have an influence in the future. The endocrine system is a vital part of coordinating and integrating the many complex reactions that make up the human psyche. Hormones are chemicals released by the endocrine glands. After being released from the endocrine glands, hormones then travel to the rest of the body via the blood stream. Hormones carry messages and help regulate bodily activities. Hormones are activators for different behaviors. Hormones can affect mood, emotional reactions, and learning ability. Changes in hormones can contribute to mental disorders like depression. The pituitary gland, often called the master gland, is located on the underside of the brain and is connected to the hypothalamus. The pituitary gland produces the largest number of different hormones and has the widest range of effects on bodily functions. The thyroid gland is an endocrine gland that produces thyroxin and is located just below the larynx...
