...The nervous system is made up of two systems that work together to help the body function. One of the systems is the Central Nervous System (CNS) which consists of the spinal cord and the brain. The other system is the Peripheral Nervous System (PNS) which is made up the nerves that connect to the rest of the body. Working together they both contribute to the wonder known as the nervous system, but how? (Better Health Channel, 2014). As said before, the Nervous system is made up of two systems, CNS and PNS. However, Neurons are microscopic cells that play a massive part in the workings of the Nervous system. What sets apart Neurons form other cells is that they can transmit electrochemical signals when stimulated. Neurons naturally have a small negative charge but when stimulated they produce enough electrical energy to create a reaction in these systems (Better Health Channel, 2014). If you have ever hurt a part of your body, say your leg, you would know that sometimes it feels like the pain is shooting up the entire leg. This is due to the Neurons being stimulated when the leg is hurt which causes a reaction in the nerves. I bet your wondering how the pain travels all the way up you leg. This is due to synapses (Better Health Channel, 2014)....

An example of this in the article was at the beginning when Jim was willing his heart rate and respiratory rate to go down, but his body temperature remained consistent. While one might think that if the heart rate and respiratory rate slowed down, the body temperature might decrease as well due to the perceived lack of blood circulation, this is not the case because the body has mechanisms in place to keep the temperature consistent even if the breathing and heart rate decrease. When Jim was...

...Case Study 1. Mr. Stevens’ symptoms, such as frequent loss of balance and the inability to even draw a straight line are indications that the cerebellum, which is part of the brain, is involved. This cerebellum is the part of the brain that has the responsibility of maintaining body balance and posture, among other things. The cerebellum is very important for body balance, as well as in body functions. This is because it plays an important role in the maintenance of body balance and posture. This is possible given that it uses the vestibular receptor in conjunction with the proprioceptors to control commands. It is the motor neurons that are responsible for ensuring that body changes as well as position are maintained (Cerebellum, nd). The cerebellum also is very important in cognitive functions. In addition, once the cerebellum has received information from the sensory system as well as the spinal cord, it regulates different voluntary movements such as speech, coordination as well as muscular activity (Knierim, n.d). Given that Mr. Stevens experiences a loss of balance, then it is definite that there must be cerebellar damage. Even more proof is added to with his inability to draw a straight line, which can be attributed to the inability of proper coordination of muscular activities. In addition, Mr. Stevens asserts that he feels like a drunken man when he is walking, this can be also linked to cognitive functions, a role that is performed by the...

...intertwined and attempt to answer basic questions of how the body and mind work together. The Four Major Psychological Perspectives The Psychodynamic Perspective The psychodynamic perspective was developed in the late nineteenth century by Sigmund Freud. He concluded that psychodynamic perspective has three key premises: 1. “People’s actions are determined by the way thoughts, feelings, and wishes are connected in their minds. 2. Many of these mental events occur outside of conscious awareness. 3. These mental processes may conflict with one another, leading to compromises among competing motives.” (Kowalski & Westen, 2011) The Psychological Perspective remains to this day heavily debated with physiologist supporting its study and other calling for its abandonment. The Behaviorist Perspective The Behaviorist Perspective was developed by accident, early in the twentieth century by Ivan Pavlov. McLeod (2007) “Behaviorism is primarily concerned with observable behavior, as opposed to internal events like thinking and emotion.” This perspective is that people have no free will and environment determines their behavior. New behaviors and reactions are learned through our interaction with our environment. We learn new behavior through traditional or operant conditioning over time (McLeod, 2007). Behaviorism was the dominant perspective in psychology...

...we behave the way we do, why we express emotion, have feelings, or experience hunger? How does it all work? The human body is comprised of systems all working together to complete an action or a coordinated set of chemical reactions initiated by the nervous system. The nervous system is part of a human’s body that controls voluntary and involuntary behaviors by transmitting information throughout different parts of the brain and the body via neurons and axons. The nervous system consists of two main parts, the central nervous system (CNS) which contains the brain and spinal cord and the peripheral nervous system (PNS) connects the brain and the spinal cord to the rest of the body. Within the peripheral nervous system you have the somatic nervous system. The somatic nervous system consists mostly of axons that transport messages from sense organs to the central nervous system and from the central nervous system to the muscles (Kalat, 2013). Also within the PNS is the autonomic nervous system, which controls the heart and other organs. The autonomic nervous system consists of two parts, the sympathetic and parasympathetic nervous systems. The sympathetic nervous system prepares organs for fight-or-flight activity such as increase heart rate, while the parasympathetic nervous system does the opposite decreasing heart rate. Both systems work together to regulate involuntary bodily functions and behaviors. One example of regulatory behavior is human reproduction and sexuality...

...in one area before progressing to another. In development stages, children experience, cognitive development, social and emotional development, language development, and gross motor skills development. Developmental milestones are talents or skills that children obtain through particular moments in time. Children develop these milestones in a chronological order. One skill must be developed before another skill can be learned or mastered. In normal circumstances, a child normally successfully achieves milestones at certain ages and stages in their lives. We all have our milestones past and future, personal and professional, individual and in common. (French 2012) Childhood Development Case Study Babies develop skills such as bonding mechanisms. They begin to recognize voices, imitate sounds. At about 6 months, they sit up alone, babble and begin making sounds. By toddler ages they walk, climb, and begin to repeat words. They begin to interact with other toddlers. As they grow they begin to develop other skills. By the time they are 4 years old, they develop social skills and begin understanding some friendships. At this age, they also mimic observed behavior from the adults in their lives. By 5 years old children are ready for school. They begin to read and write. They understand rules at this age in development. By age 10, children recognize right from wrong. By 12 years old, children are beginning puberty....

...what have made the foundations and history of psychology. The field of psychology started in the late nineteenth when researchers became to experiment and explore what they believed caused the mind to function. The two earliest ideas and thoughts were structuralism and functionalism. Structuralism came about by Edward Titchener, he basically studied the basic thoughts and ideas of consciousness or the mind (Kowalski & Westen, 2009). He thought that if he studied everything that came through the mind, it would give a good insight as to how the mind functioned. Functionalism on the hand studied the functions or processes that came about in helping people adapt to environments. William James, one of the founders, believed that the actual study and observation of people and animals could help discover why they behaved the way they did. It emphasized that people were different (Calkins, 1906). From these two theories and ideas came many other perspectives or schools of thoughts. These are the ones that are better known in today’s society. The first is the psychodynamic perspective, which was brought about by Sigmund Freud. This perspective is based on three main ideas. Those are that people’s actions are...

...1.1 Introduction Multiple sclerosis is a disease of the central nervous system, harms the brain's ability to send and receive signals. It is considered one of the common diseases of the central nervous system. It affects in most cases the children and people aged between 20-40 years. Multiple sclerosis (MS) is an inflammatory disease of the central nervous system. The central nervous system is made up of the brain, spinal cord, and optic nerves. The exact reason(s) for the inflammation that occurs in MS are not yet known, and this remains an active area of research. We do know that the inflammation damages both neurons and the myelin that protects neuronal processes (called axons). The effect of multiple sclerosis (MS) on the individual and...

...Opium, a highly addictive narcotic consumes a reddish-brown color to the eye and is very heavily scented; prepared from the opium poppy. It has been used as an analgesic and an antispasmodic. While opium is made up of a “cocktail” of drugs, the most active is morphine. In recent years, other derivatives for example heroin have been widely used.(IC) Studies have shown that as many or up to 50 alkaloids can be derived from opium and further processed. It distinctively originates from two groups, phenanthrones and morphine, in which I morphine is the most prevalent alkaloid, formulating up 10-16% of the entire drug(IC). Opioids are primarily used to treat pain, but if often abused for a euphoric feeling it causes. Opium can be consumed several different ways, the most common and traditional way is by ingestion. Smoking opium allows for the effects to be more controlled, as it is not really smoked, but vaporized. Another common method of administration requires making opium in the form of a tea and drinking it. This method is more dangerous than inhalation...

...essay psy 340 wk 1 individual assignment Biopsychological Essay Biological psychology is combining psychology with biology and studying what kind of impact biology plays in our behavior. In other words, how does the physical brain affect our psychological behavior? It is a biological approach to the study of psychology. This has also been referred to as psychobiology, behavioral biology, or behavioral neuroscience Biopsychology did not develop into a discipline o f its own until the 20th century. While the exact date s not clear, in 1949 the publication of “The Organization of Behavior” by D.O. Hebb. This publication was significant in its emergence in bringing biopsychology to the forefront of study. In this book Hebb's theory was about the complex psychology such as perceptions, emotions, thoughts, and memories might have a strong influence from actual brain activity. Hebb based his theories on experiments of humans and laboratory animals, clinical case studies, logical arguments, and his own observations of daily life. To go back even further, we can look at Aristotle, or Plato. While it may not have been considered as a study of it’s own, we should not forget their early contributions. It is the very beginning of taking a look at the brain as the key to all thoughts, behaviors, and philosophical thoughts. Aristotle looked at the brain in ways that were not yet considered.
