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

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

Information travels along the axon in the form of an electric charge called the action potential. terminal buttons Tiny bulblike structures at the end of the axon‚ which contain neurotransmitters that carry the neuron’s message into the synapse. action potential vs. resting potential action potential The nerve impulse caused by a charge in the electrical charge across the cell membrane of the axon. When the neuron "fires"‚ this charge

Linear acceleration Smell Taste Touch – Pressure Warmth Cold Pain Joint Movement and Position Muscle Length Muscle Tension All sensory information arrives at the central nervous system (CNS) in the form of action potentials and the stronger the stimulus‚ the higher the frequency of action potentials. For example‚ touch‚ pressure‚ pain‚ temperature and taste sensations arrive at the primary sensory cortex. The CNS interprets the nature of the sensory information entirely on the basis of the area of the

The Cardiovascular System: Intrinsic Conduction System 1. The intrinsic conduction system consists of __autorhythmic cardiac______ cells that initiate and distribute __impulses___ throughout the heart. 2. The intrinsic conduction system coordinates heart activity by determining the direction and speed of _heart depolarization___. This leads to a coordinated heart contraction. 3. List the functions for the following parts of the intrinsic conduction system: a. SA Node __initiates the depolarizing
