...of the central nervous system (CNS)? The central nervous system, also known as the CNS, consists of three(3) major components of the human body: * Brain – the brain is made up of three(3) parts: the cerebrum, the diencephalon, and the hindbrain. * Nerve Tissue – this part of the CNS is comprised of neurons, synapses, and neurotransmitters. * Spinal Cord – protected by vertebrae in the back, the spinal cord is made up of fiber tracts and spinal nerves. (Pedersen DD; PsychNotes: Clinical Pocket Guide, 3rd ed, F.A. Davis Company, 2011, Ch. 9, pg. 1) One of the two major divisions of the human body’s nervous system, the central nervous system is responsible for integrating sensory information and responding accordingly. In other words, its job is to get information from the body and send out instructions to the body. * What is the job of the peripheral nervous system (PNS)? The peripheral nervous system, or PNS, is made up of two(2) components of the human body: * Afferent System – this system is made up of somatic and visceral sensory neurons. * Efferent System – this part of the PNS controls the somatic nervous system (somatic motor neurons), as well as the parasympathetic nervous system, both of which are made up visceral motor neurons.

Main body system • Skeletal System • Muscular System • Nervous system • Respiratory system • Digestive System • Male Reproductive System • Female Reproductive system • Cardiovascular system • Urinary system • Endocrine system 1. Skeletal system The skeletal system is muscle that is connected to the skeletal to make a part of the mechanical system which moves the limbs and other parts of the body. The skeletal also relates the cartilages and joints of the human body which then creates the human skeleton. It is one of the main and important systems in the body. The joints are very important because they allow different types of movements at different locations to happen. However there are three components; • Bones • Cartilages • Joints Bones: Bones is a tough and frim form of connective tissue. It is the responsibility is to almost all strength of skeletal. Bone is the mineralization factor. Bones are highly mineralized with calcium salts Cartilages: The cartilage is a form of the connective tissue however it is not as tough and frim as the bone and the main difference in the cartilage and bone is the mineralization factor. This is because the bones are highly mineralized with calcium salts whereas cartilages are not. Joints: the joints are important components of the human body because they allow the body to move about...

...wonder why as humans 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...

...Introduction A system is made up of different tissues and organs working together to perform a specific function in the body. Skeletal system: Skeletal system is the system of bones, associated cartilages and joints of human body. Together these structures form the human skeleton. Skeleton can be defined as the hard framework of human body around which the entire body is built. Almost all the hard parts of human body are components of human skeletal system. Joints are very important because they make the hard and rigid skeleton allow different types of movements at different locations. If the skeleton were without joints, no movement would have taken place and the significance of human body no more than a stone. Components of Human Skeleton Human skeleton is composed of three main components; Bones, Associated cartilages and Joints. Bones: Bone is a tough and rigid form of connective tissue. It is the weight bearing organ of human body and it is responsible for almost all strength of human skeleton. Cartilages: Cartilage is also a form of connective tissue but is not as tough and rigid as bone. The main difference in the cartilage and bone is the mineralization factor. Bones are highly mineralized with calcium salts while cartilages are not. Joints: Joints are important components of human skeleton because they make the human skeleton mobile. A joint occurs between “two or more bones”, “bone and cartilage” and “cartilage and cartilage”. Divisions of Human Skeleton: Human skeleton...

...schools of thought are known as the psychodynamic, behaviorist, cognitive and evolutionary perspectives. They came up with these by research and study which will be discussed throughout this paper. In many respects, these perceptions have progressed independently, and at the center of each are singularities the others tend to ignore (Kowalski & Westen, 2011). Despite their differences, each school of thought sought evolution for psychology as well as advancement of human understanding while remaining focused on the unique characteristics of contemporary psychology. Psychodynamic Perspective. The psychodynamic perspective belief is that most of the mental processes and emotions happen at the unconscious or subconscious levels, meaning below conscious awareness. Sigmund Freud was one of the most influential thinkers in the early twentieth century whose work in the psychodynamic perspective influenced many in the early stages of the science of psychology. The main notion of Freud’s theory was that the human mind consisted of three basic components: the id, the ego, and the superego (Kowalski & Westen, 2011). Freud believed that when these components conflict, an internal struggle ensues, negatively affecting behavior. The Behaviorist Perspective. Pioneered by...

...The nervous system is the control center of the whole body. Nerves are alot like wires that carry signals or impulses throughout the body. Inside each nerve is a bundle of nerve fibers. Some nerves are longer than other nerves, these are the type of nerve that go from the top of your body to the bottom of your body. Nerve cells are called neurons. There are two main types of nerves: motor nerves and sensory nerves. Motor nerves are used by the brain to control all the muscles throughout our body. The brain sends signals via the motor nerves to tell us what to do what is certain situations. For instance when we are lifting weights the brain obviously knows to push harder instead of not push at all. There are the things that we do every day....

Neurons carry and transmit electrical impulses generated by both internal and external stimuli. B. What is the difference between a neuron and a nerve? Neurons are the cells that exchange messages from the internal and external environments. Nerves consist of many neurons that transmit different signals to the brain. They form structural and functional units of the nervous system made up of neurons. C. What gives a multipolar neuron its name? It is named multipolar because of the multiple branches, processes, and extensions that stem off the cell bodies. D. What are the functions of the dendrites and axons? Dendrites receive incoming signals for the nerve cell. Axons carry outgoing signals of the cells to other cells in the body. Exercise 2: Structures of selected neurons A. Which slide contained bipolar neurons? The pyramidal cell slide. B. Which slide contained unipolar neurons? The dorsal root ganglion slide. C. What was unique about the dorsal root ganglion compared to the other two slides? The dorsal root ganglion was more round in shape compared to the perkinje and pyramidal cell slides.

...The Science of Psychology Foundations of Psychology Suzette Lee [ Monday, April 02, 2012 ] PSY300 Psychology is a scientific study that investigates the main components of the brain, the mind and the body in different fields of psychology in order to understand and conduct observations of the mental process of the human mind, and observable behavior. Psychology is often used to understand the unknown of human behavior, and their potential patterns that observe the actions of self expression on how people feel and store memory. The study of the mind is an observation of a person’s mental awareness of both the conscious and unconscious mentality. Structuralism was the dominant school of psychology in Germany and the U. S. between1890-1920, and was the school of thought based on the notion that the object of psychology is to analyze consciousness into its basic elements and investigate how these elements are related. Structuralism explores areas of the mind, focus mainly with sensation and perception in vision, hearing and, touch through introspection, or the systematic observation of one’s own conscious experiences, although Functionalism was the protest against structuralism and had the assumption that functionalism was more practical and concerned with commonsense issues, structuralism believed that mental functions were not subject to introspective analysis which it was the shaping of the mind that could be analyzed. Another school of thought is behaviorism, in which...

...structure and function of the 11 systems within the human body. It will detail the interrelationship between the nervous system and the musculoskeletal system and between the circulatory system and the lymphatic system. It will then explain the roles of the circulatory and lymphatic systems in the immune response and the role of hormones in metabolism. Human Body Systems The human body is made up of 11 separate but interconnected systems (Sherwood, 2007). These are the skeletal, muscular, circulatory, respiratory, digestive, excretory, nervous, integumentary, immune, endocrine and reproductive systems. The success and survival of the human body is dependent on the ability of separate body systems to work together. The skeletal system provides structure for the human body, stores minerals, produces blood cells and provides protection for delicate organs (Kelly, 2004). 206 bones are connected with ligaments, muscles and tendons, with cartilage, a softer cushion like material, providing protection in jointed areas. Body movements are controlled by the muscular system, with these muscles being connected to bones via tendons (Adams, 2004). Stimulation of these muscles by the nervous system causes contraction and the resulting movement of bones to which they are attached. A number of involuntary muscles ensure the respiratory and circulatory systems continue with contraction of the heart and lungs (Adams, 2004). The heart is central to the circulatory system and acts as to pump blood...

...| The foundations of psychology | | | Blaine Waddell | 5/29/2011 | PSY/300 Katherine Bowen | Psychology is a science of behavior and mental functioning that uses both quantitative and qualitative research studies to develop and test hypotheses and put forward theories and models that explain human behavior.” (Kowalski & Westen, 2005) When psychology was first founded there were only a few foundations of psychology. The most popularly used in the 1800’s were called, structuralism and functionalism. Structuralism focuses on identifying and analysis basic elements of experiences. These experiences even include mental events like perception. Research for this form of approach to psychology comes from verbal accounts of experiences. Functionalism focuses on the belief that optimal learning conditions can be created by knowing how the brain uses and processes information; thereby it is considered perceptional also. As time went on and the science of psychology progresses more approaches to present day psychology emerged. Behavioral, psychoanalytic, cognitive, social/cultural, humanism, physiological, and clinical are all popular approaches to modern day psychology. The physiological approach is the learning how the brain effects behavior and how behavior can affect the brain. The behavioral approach...

...BIO-REGULATORS OF HUMAN BEHAVIOR Human beings – products of biological functions and their behaviors are influenced by many factors (one of these factors is biological or physiological) Nervous system & Endocrine system (both biological & physiological) – regulators of human behaviors. The Nervous System * Most complex and elaborate system of biological structure in the human body. It regulates the behavior of an individual to make him survive. Neuron – the basic unit of the nervous system Producing and transmitting electrical and chemical signals from a stimulus to a response. (Distinct parts: dendrites, soma, axon, myelin sheath, nodes.) Dendrites – fine and tiny hairlike structure looks like a branch of a tree. They receive nerve impulses (messages/information which are electrical in nature) for nearby neurons and send the information to the cell body (the process is called axonal transmission) Cell body or soma – contains the nucleus that provide energy for transmitting the stimulus received from the dendrites to axon. It performs work of metabolism. Axon – found at the other end of cell body. It carries away the stimulus to Another neuron. *There is only one axon in neuron. (process of transmitting info from neuron to neuron is called synaptic transmission) Myelin sheath – fatty material that covers and protects the axons. Its function is tospeed up the conduction of nerve impulses. Nodes – they serve as break on the momentum of the speed...

Copyright © 2011 by Pearson Education, Inc. 3.1 ■ General Layout of the Nervous System I n order to understand what the brain does, it is first necessary to understand what it is—to know the names and locations of its major parts and how they are connected to one another. 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 payoff for your effort will be a fundamental understanding of the structure of the human brain and a new vocabulary to discuss...

...centred on how this relates to previous technological innovations and their early acceptance, e.g. the telephone. 1. Introduction Technology is now becoming available which is opening up the realistic possibility of thought communication between individuals being achieved in the forthcoming decade, through the use of brain-computer implants. Indeed the first trials along these lines are even now occurring in several research labs [Kennedy et. al., 2000; Warwick et. al., 2004]. New technical methods presently being looked into (e.g. nanotechnology) are only likely to further enhance the results obtained thus far and speed up the rate of progress in this area. Witnessing the dawning of a completely new and revolutionary technical capability for humans raises a multitude of questions in terms of the effects on all aspects of society. It is interesting to consider what we can learn by looking back to relevant new directions when they have occurred in the past. In this paper we make an attempt to indicate the chief areas of interest and have a stab at pointing to pertinent events that, we feel, relate to the situation as of now, and from which we may take heed. It is always extremely difficult, given any new technological discovery or invention, to realistically assess its potential future impact on and in society. Hindsight is a...

...Foundations of Psychology PSY/300 General Psychology June 3, 2013 Foundations of Psychology Modern psychology combines four major and distinct schools of thought, with each one containing possessing fundamental assumptions. Even though each individual perspectives maintains it distinction and individuality, they all have made influences to the developing science of psychology. (Kowalski & Westen, 2011). While they each focus on a different domain and function, each of them remain 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...
