Definitions of the words: “Anatomy”: the structure or study of the structure of the body and the relation of its parts to each other. “Physiology”: science that deals with the functions of an organism or its parts. “Psychology”: the scientific study

201-104 November 11‚ 2010 Part I: Meet Annie 1. What vital signs or symptoms does Annie exhibit? a. Blurred vision and eye strain b. Hands ache and feel weak c. Gasping for air d. Weakness & Constant fatigue 2. Can you see any common features in Annie’s signs and symptoms? With blurred vision and eyestrain we must look at the optic nerve within the brain. From there‚ what could be causing the difficulty breathing and weakness? It must be a neurological problem

What is psychology? The scientific study of behavior and mental processes Development of psychology as a science Wilhelm Wundt founded the first psychology laboratory. Student of Wudnt ’s‚ E.B. Titchner named Wundt ’s approach structuralism. William James gave field an "American Stamp‚" invented functionalism Contemporary approaches to psychology Biological Approach (focus on the body) Neuroscience Behavioral Approach (behavioral responses and their environmental determinants) Psychodynamic

Vanessa Yang Smith Period 6 Biology HP 17 March 2014 Biology Study Guide: Unit 6 Physiology III Benchmark 1. Homeostasis maintains and keeps a balance of an organism’s internal environment. 2. The body maintains homeostasis by the feedback inhibition‚ in which a stimulus produces a response that opposes the original stimulus. 3. The axon terminal is the nerve ending. The nodes speed up the message. The myelin sheath is an insulating membrane. The axon carries impulses away from the cell body

NEURONAL DIVERSITY - Categories of neurons of CNS: 1. Afferent/ sensory neurons – convey information from periphery to CNS 2. Motor- sends commands to muscles and glands 3. Interneurons – most abundant signalling elements in the CNS ( process information locally or convey information from one region of CNS to another • Types: a. Local interneurons/ internuncial neurons/ local circuit neurons – short axon Golgi type II (greatly outnumber type I in CNS)

receptor in the membrane‚ and the removal of the transmitter form the synaptic cleft. The nervous system makes use of two types of neurotransmitters: small-molecule transmitters (acetylcholine‚ amines and A.A) and neuroactive transmitters(peptides) 2. Neurons have developed a sophisticated ability to regulate the synthesis‚ storage‚ release‚ and degradation (or removal) of neurotransmitters to achieve the desired levels of transmitter molecules. In general‚ each of these processes is specific to
