nervous system. The bushy‚ branching extensions of a neuron that receive messages and conduct impulses toward the cell body. The extension of a neuron‚ ending in branching terminal fibers‚ which messages pass to other neurons or to muscles or glands. A layer of fatty tissue segmentally encasing the fibers of many neurons A neural impulse; a brief electrical charge that travels down an axon. The axon potential is generated by the movement of positively charged atoms in and out of channels

THE BIOLOGY OF MIND Chapter 2 SQ3R (Survey‚ Questions‚ Read‚ Retrieve‚ Review) QUESTIONS: BIOLOGY‚ BEHAVIOR‚ AND MIND 2-1: Why are psychologists concerned with human biology? By studying the links the behavior and biology‚ psychologist work from a biological perspective. This perspective shows the psychologist which areas of systems interact to influence behavior. Humans are biopsychosocial systems‚ in which biological‚ psychological‚ and social-cultural factors interact to influence our

Depression is a mood disorder and the biomedical model portrays one way in which it can be understood. The biomedical model focuses on biological factors alone in an attempt to explain an illness or a disorder. It describes illnesses as disturbances within the human body that can be altered and corrected. Very unlike the biopsychosocial model‚ it doesn’t include other factors that may contribute to a disorder such as their psychological state or their social context. The biomedical model focuses
