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...

...Chapter 11 question 9 Describe and give function of a neuron cell body, a dendrite and an axon. Neurons are organized to form complex networks that perform the functions of the nervous system. They are also called nerve cells. The function of neurons is to receive stimuli and transmit the action potential to other neurons or the effector organs. There are three parts to a neuron that include; a cell body and two processes known as axon and dendrites. The cell body is call neuron cell body. It contains a single, relatively large and centrally located nucleus that has a prominent nucleolus. The nucleus is surrounded by rough endoplasmic reticulum and Golgi apparatus. Cell body also contains other organelles and mitochondria.Cell body differs...

...Chapter 5: The Skeletal System 1. List six functions of the skeleton. a. Support b. Movement c. Protection d. Storage of minerals e. Fat storage f. Blood cell production 2. Compare compact and spongy bone. Compact bone is dense bone with very few spaces and is covered by a nourishing membrane called the periosteum. Spongy bone is identified by its many spaces that are filled with red bone marrow, which produces red blood cells. 3. Describe the structure of a long bone. Where are the yellow and red marrow found in adults? A long bone in the human body contains both compact bone and spongy bone. The compact bone is found on the outer surface of the bone and compose the shaft. The spongy bone is found at the ends of the long bone. Yellow bone marrow it found in the central shaft of the long bone surrounded by the compact bone. Red bone marrow is found in spaces of the spongy bone. 4. Describe the structure of an osteon, and explain the function of osteocytes and the central canal. The osteon consists of a central canal surrounded by concentric rings of osteocytes (mature bone cells) in a rigid matrix. O steocytes are located within a lacuna in the matrix. Canals connect the lacunae to each other and to the central canal. This allows for the transport of items between the cells and the blood vesels in the central canal. 5. Describe the formation of bone in a fetus. Explain how bone growth continues after birth. During fetal...

...Steven Harris Intro to Psych MWF 8-850 2/14/14 Chapter 2 the Brain Every human has the same amount of brain, which is three pounds solid. The brain is connected to the CNS (Central Nervous System) and the PNS (Peripheral Nervous System). The CNS is the processing center of the nervous system. Two main organs of the CNS are the brain and the spinal cord. The brain processes and interprets sensory information sent from the spinal cord. The CNS receives information from and sends information to the PNS. The peripheral is all of the nerves and others that go outward from the spinal cord. In these nervous systems, there are neurons. Neurons act as signals for the brain and transmit information. The brain makes up 2 percent of the total body weight. It has been found that the brain has 1 trillion neurons. With talking of the brain, there is controversy on the subject of the sides of the brain. The left side of the brain is said to be the side which has to do with spoken language, math, logic, etc. The right side of the brain is the side that has to do with the artistic matters. There are also different parts of the brain. The cerebrum, is the largest part of the brain. The cerebrum has two hemispheres, right controls left, and left controls right. The cerebellum, is the second largest part of the brain, which regulates correlation, balance, and movement. The cerebellum makes up 20 percent of the brains mass. There is also the thalamus, which just acts as a relay station for...

Wilhelm Wundt, founder of psychology as discipline. Conscious experience and building blocks, trained many early psychologists 2. Identify the following, and the one or two main names (if applicable): Structuralists, Functionalists, Gestalt Psychology, Behaviorism Psychoanalysis, Humanistic Psychology, Cognitive Psychology b. Structuralists: Titchener- Wundt’s student. Wanted to examine the structure of mind and organization of basic elements of sensations, feelings, and images. “Structure of the mind” Example: I see a square as composed of four separate lines. Introspection: observing ones own conscious reactions. c. Functionalism- William James- first American psychologist. “Mental associations allow us to benefit from previous experience.” Deals with function, what does consciousness does to us, what is the purpose etc. d. Gestalt psychology- Max Wertheimer. Objects are well-organized structures, whole objects instead of parts. Ex. A square is a Square e. Behaviorism psychoanalysis – Sigmund Freud. Founded psychoanalysis in early 1900s, focused on unconscious thoughts in determining behavior. Psychoanalysis- feelings come from a hidden place in your mind called unconscious. f.
