Introduction
The brain is such an awesome machine with so many intricate working parts and components all working together at the same time for optimal functioning. Pinel, J. (2011) describes the neurons and synapse as highways and byways that seem to haul information and travel them to the body for several different functions. This essay will explain five parts of the brain, the Myelencephalon, the Met encephalon, the Mesencephalon, the Diencephalon, and the Telencephalon which all structure and cause different functions in the body. Myelencephalon The Myelencephalon is the part of the brain that has many functions; for example it causes all autonomic functions. Another function is the breathing portion of the body and the paths that all of the nerve tracts take as well. Digestion, Heart Rate, Swallowing, and Sneezing are also functions of the Myelencephalon which are all located in the brain stem and structured on the medulla oblongata. It seems that this portion of the brain carries many signals to the brain and throughout the body. Metencephalon According to Nakamura, H. (2008), “Primary brain vesicles such as the prosencephalon, mesencephalon and metencephalon are made and subdivided into secondary brain vesicles: the telencephalon, diencephalon, mesencephalon, metencephalon and myelencephalon (P.113).” Essentially the Metencephalon is the place where the structures called pons are located which is located on the brain stems top layer. According to Nakamura, H. (2008), the pons are the way to the brain’s cerebellum, which is another structure all in itself. The basic function for the Metencephalon seems to be for motor coordination but in the study conducted by Nakamura, H. (2008),it was noted that motor skills such as the movement of

The Brain Week 2 Psy 240

...The Brain Week 2 Psy 240 Biopsychology The human brain is ultimately responsible for all thought and movement that the body produces and is one of the largest and most complex organs in the human body composed of trillions of connections that work together called synapses. The brain weighs approximately three pounds and is made up of nerve cells which interact with the rest of the body through the spinal cord and nervous system. It contains about 75 percent water along with 100 billion neurons. Neuroscientists estimate that there are 100 trillion connections among the neurons, and nearly an infinite number of paths that neural signals can travel through parts of the brain called the morass. These nerve cells transfer information back to the center of the brain where information is processed, generated and appropriately reacted upon. The human brain gives us the ability to move, generate information, to speak and understand language, to interact with the environment, to interact with inanimate objects and to communicate with others. The brain can be divided into three basic units: the forebrain, the midbrain and the hindbrain. However, there are also five major structures of the brain. The Myelencephalon, Metencephalon, Mesencephalon, Deincephalon and Telencephalon. These five major structures of the brain shed some light on the complexity of how it is structured and how the human brain works. The Myelencephalon, also called medulla, is the division of the brain...

The Brain Psy/240 Week 2

...The Brain The brain is split up into several different parts or structures in order to better understand how things are laid out and how they work. The simplest way to separate the different parts of the brain is into the forebrain and hindbrain, with the forebrain also being called the cerebrum, and the hindbrain being better known as the brain stem. The brainstem is best known to be in charge of involuntary and gross motor functions, such as breathing, muscle control, and digesting food. The cerebral cortex is in charge of more complex things such as thought and memory. Aside from this general way to split up the brain, it can be broken down further into five major structures, each with it’s own physiology and structures within it. These regions are the telencephalon, diencephalon, mesencephalon, metencephalon, and myelencephalon. The telencephalon sits at the top of the brain and is divided into two hemispheres, often referred to as cerebral hemispheres (Pinel, 2011). It is the biggest of the five major structures, and is in charge of the brain’s most complex functions (2011). Along with housing the structures that are in charge of memory and thought, the telencephalon is also the part of the brain that controls voluntary movement, taking in outside sensory stimuli, and facilitates complex thought processes such as retaining new information, processing language, and problem solving (Pinel, pg. 66, 2011). Within the telencephalon is the cerebral cortex. The cerebral cortex...

The Brain

...through electrical currents. Similar to our brain and body, the brain carries out functions through our nerves. The brain gets information, processes that information, and then sends it out to the rest of the body. A large amount of information is put out to the body through the spinal cord, telling the body to do voluntary and involuntary acts. The brain is broken down into three swellings with five structures, the forebrain consists of the telencephalon, and the diencephalon, the midbrain consists of the mesencephalon, and the hindbrain consists of the metencephalon and the myelencephalon. The three swellings of the brain are the forebrain, the midbrain, and the hindbrain. The forebrain is the anterior of one’s brain. The midbrain is the small central part of the brain stem. The hindbrain is the lower part of the brain stem that compresses the cerebellum, the pons, and the medulla oblongata. These three swellings develop as a person ages and becomes adults. The first structure of the forebrain is the telencephalon, which is the largest part of the brain and controls the most difficult functions. It controls the voluntary actions that the human makes, like the ability to learn, the ability to speak, and knowing how to solve problems. This structure also controls one’s level of intelligence, one’s personality, and begins able to smell, and touch. The telencephalon is made up of many structures, the cerebral cortex, major fissures, major gyri, four lobes, the limbic system, the...

... * * * * * There are five major divisions which hold a specific function in the brain. These major divisions or structures are very important and can often be described or compared to neighborhoods or districts due to how they have different locations in the same area. The early development of the brain begins explaining the five major divisions and what each one does in particular. In the vertebrate embryo, the tissue that eventually develops into the CNS is recognizable as a fluid-filled tube. The first indications of the developing brain are three swellings that occur at the anterior end of this tube (Pinel, 2011). These three swellings with time develop into what is known as the forebrain, midbrain and hindbrain. Before birth, the three swellings in the neural tube become five which occur when the forebrain swelling grows into two different swellings just like the hindbrain. The five swellings then make up the brain at birth. These five sections or swellings are known as the Telencephalon, Deincephalon, Mesencephalon, Metencephalon and Myelencephalon. * The Myelencephalon, also known as the Medulla Oblongata, is located in the most posterior division of the brain (Hindbrain). The Mylencephalon is responsible for delivering signals between the brain and the entire body and responsible for reticular formation. Reticular formation is known for its net-like appearance that occupies the core of the brain stem and parts of it play a role arousal as well...

Which is composed of trillions of connections that all work together called synapse. The adult brain weighs about 3 pounds, which is a major growth being that the human brain weighs about 350 grams at birth. The brain is made up of nerve cells that interact with the rest of the body through the spinal cord and nervous system. The nerve cells transfer information back to the center of the brain where information is processed, generated and appropriately acted upon. Without the human brain we wouldn’t be able to move speak or understand different things. The brain can be divided into the forebrain, mid brain and the hindbrain. But there is five major structures of the brain, which are Myelencephalon, Metencephalon, Mesencephalon, Diencephalon and Telencephalon. Myelencephalon also known as medulla, is the most posterior division of the brain. Myelencephalon is composed of tracts that carry signals between the rest of the brain and the body. It’s complex network of about 100 tiny nuclei which occupies the central core of the brain stem from the posterior boundary of the midbrain. The tiny nuclei are very important they are responsible for many things such as movement, maintenance of muscle tone, attention and even us sleeping. Accordingly...

...The Brain The Five Major Structures of The Brain At the beginning of birth there are initially three swellings in the human brain. Once adulthood is reached the brain develops two new swellings. The forebrain and the hindbrain grow into two different swellings, this is how two more are added while becoming an adult. Once as an adult the brain consists of five structures that make up the fore, mid, and hindbrain from anterior to posterior. These five structures are the Telencephalon, the Diencephalon, the Mesencephalon (mid-brain), the Metencephalon, and the myelencephalon. Myelencecephalon The Myelencephalon is the posterior part of the brain, also known as the medulla. It is composed largely of tracts carrying signals between the brain and the rest of the body. An interesting part of the Myelencephalon is called the reticular formation. Reticular formation is a complex network of around 100 tiny nuclei that occupies the central core and also the brain stem from the posterior boundary of the Myelencephalon to the anterior boundary of the midbrain. This part of the brain even plays a role in arousal which is why it is sometimes referred to as reticular activating system. However, this term can be misleading because the nuclei of the reticular formation are involved sleep, attention, movement, the maintenance of muscle tone, and various cardiac, circulatory, and respiratory reflexes.

...The Brain Terrie Oliver Axia College of University of Phoenix The Brain The brain is part of the central nervous system, which is located in the skull, and a very complex organ, with massive information data that flows throughout the body. The brain is like a hard-drive: storing daily active, awareness, memory, emotions, and reason. The brain is where decision-making is done, right, or wrong, what could have been, or should have been. The brain with all its mysterious complexities, and abilities, is one of the most study organs in the human body. The brain is divided into five divisions: the forebrain contains the Telencephalon, and the Diencephalon. In the midbrain we find the Mesencephalon, and in the hindbrain the Metencephalon, and the Myelencephalon are found. These five structures also contain divisions in their selves adding to the complexity of the human brain as we discus their functions (Pinel, 2007). The Telencephalon The Telencephalon, or cerebrum as referred to by many people, is located in the forebrain, divided into two hemispheres, is the largest of the structures, and can be compared to junction box at a train depot. Train cars are like the sensory input, and output that goes into the telencephalon, which like the junction box directs these senores, or train cars where to go. These functions could be voluntary movement, learning, solving issues, or problems, and speaking. There are other divisions found in the telencephalon and they have...

This chapter introduces you to these fundamentals of brain anatomy. Before you begin this chapter, I want to apologize for the lack of foresight displayed by early neuroanatomists in their choice of names for neuroanatomical structures— but, then, how could they have anticipated that Latin and Greek, universal languages of the educated in their day, would not be compulsory university fare in our time? To help you, I have provided the literal English meanings of many of the neuroanatomical terms, and I have kept this chapter as brief, clear, and to the point as possible, covering only the most important structures.

...The Brain Kelly Hart PSY/240 February 14, 2016 Pamela Reeves The Brain The brain is such a fascinating and complex area of the human anatomy. Let’s take a few minutes to learn about the five major structures of the brain, and what they do. As we begin, let’s take a look at the telencephalon first. The telencephalon is part of the cerebral hemisphere, located in the forehead, and is by far the largest division of the brain. The telencephalon, along with the help of the cerebral cortex, the basal ganglia, the hippocampus, and the amygdaloidal nucleus control an array of functions. The telencephalon is instrumental in promoting our language function, voluntary movements, takes in and assesses sensory input, and reconciles complex cognitive systems like learning problem solving, and as mentioned above, language. The basal ganglia located within the telencephalon and the diencephalon contributes to motor function. The hippocampus and the amygdaloidal nucleus located in the lower cortex, play an essential role in emotional expressions. The cerebral cortex brings the telencephalon, basal ganglia, hippocampus, and amygdalin nucleus together coordinating all their functions and maintain the memory of these functions. The diencephalon is divided into two elements: the thalamus and the hypothalamus. The diencephalon is located in the forebrain, and controls a lot of the autonomic functions (subconscious functions) of the peripheral nervous system. The thalamus is a two lobed area...

Nervous System

...The Nervous System and Special Senses Abstract This paper contains a brief discussion on the overview of the nervous system and the organs that play a major role in the system. It goes into further detail of the nervous system by separating into the central nervous systems and its functions, the peripheral nervous system and its two branches under the system; including what it is responsible for and briefly how it works. The paper then discusses the special senses. It focuses on the eyes and ears and how they function to perform their major duties. The Nervous System and Special Senses One of the most complicated systems of the body, the nervous system is responsible for many different body functions. It is composed of two primary cell types-neurons and neuroglia. The neurons are responsible for transmitting impulses to different parts of the body. The neurons are usually identified by the way they travel, such as afferent (sensory) - moving toward the brain or spinal cord, or efferent (motor) -moving away from the brain or spinal cord (Nervous System and Special Senses). The neuron is a special structure in itself. It is composed of a cell body, a nucleus, dendrites, axons, and a myelin sheath. The dendrites carry impulses to the cell body, while the axons carry the impulses from the cell body and out to muscles, glands and other dendrites. Neuroglia is much simpler than neurons. Their main function is to support the neurons and bind them to other neurons or tissue...

What Are Personality Theories

...they are. Theories categorize people on characteristics or traits, and then try to describe the effect that this has on a person’s behavior in certain situations. Personality theories are supposed to focus on how people differ from one another; theories select behaviors or characteristics to determine their taxonomies or categories. Biological theories of personalities focus on genetics as well as biological relationships in physiological arousal and the neurochemistry in our brains. The biological approach to studying a person’s personality would be the differences in brain chemistry in extrovert and introverts. Theorist use biological processes to fill in the gap between personality and genetics by theorizing biological effects with behaviors. This anatomical approach examines the functions of brain structures. One of the biggest pioneers in the field was Eysenck; he attempted to relate personality to biology. Eysenck theory is complex, but it has grown over the years, one basic assumption is the brain has excitatory and inhibitory neural mechanisms. The balance between these two produces levels of psychological arousal at any given time. The dispositional theory is the classic or traditional way of psychological study of personalities. Since the early Greeks, maybe even longer it has been recognized that people are different not just physically, but psychologically as well. The dispositional theory shows system for classification and describing psychological characteristics...

...500 to 800-words for the entire worksheet. Part I: Origins of Psychology Within psychology, several perspectives are used to describe, predict, and explain human behavior. Describe three major psychological perspectives and name at least one leading theorist for each. Three major psychological perspectives are behavioral, sociocultural, and cognitive. The behavioral perspective views behavior as the result of environment experience. Environmental experience is basically all of a person’s life experiences that they have been subjected to in the past, and also the new experiences that will take part in their behavior. The behavioral perspective gained great momentum in the 20th century because it was a powerful tool in training, education, and industry. Critics claimed that behaviorism was dehumanizing. (John B. Watson, http://www.ccis.edu/, 5/17/13) and others conducted a thorough explication of Classical Conditioning and B. F. Skinner, responding somewhat to the critics of behaviorisms dehumanization, explained and expertly defended the processes of Operant Conditioning. Basically based off of a person’s environment will depict the way that they may behave. The cognitive perspective focuses mainly on the cognitive processes that are involved in learning, also on how a person’s brain works. It’s a form of psychology that examines internal mental processes such as a person’s perception, their thinking, their language, memory, problem solving and creativity. Cognitive psychologists...

The Importance of Biology in the Study of Psychology

...trying to understand the functions of the brain. The body and mind connection and how it reacts to certain behaviors or illnesses. Most all psychological functioning can be reduced to underlying brain processes. This should serve as reason alone as to why biology plays an important part in the study of psychology. Psychological factors play a role in whether a person develops a mental illness and in how well they recover from a mental illness, yet biological and genetic risk factors, or predispositions, are fundamentals to understanding mental illnesses. In this paper, we will look at Parkinson’s disease as an example of how biology has brought us to a deeper understanding of the psychology of mental illness. Psychology is an academic and applied discipline that involves the scientific study of mental functions and behaviors. Psychologists attempt to understand the role of mental functions in individual and social behavior, while also exploring the psychological and neurobiological processes that underlie certain functions and behaviors. For this reason, biology plays a very important role in the study of psychology. Psychology determines what people perceive to feel and behave, but underlying it all, ultimately determining the way we act, feel and behave, is biology. A biological perspective is relevant to psychology in the study of how the nervous system and hormones work, how the brain functions and how changes in structure and/or function can affect behavior (McLeod...
