AP PSYCHOLOGY

Detailed explanation-1: -The central nervous system has a fundamental role in the control of behavior. It contains the brain and the spinal cord which are both encased in bone which shows their importance. Both the brain and spinal cord receive signals from the afferent neurons and send signals to muscles and glands through efferent neurons.

Detailed explanation-2: -Your nervous system guides almost everything you do, think, say or feel. It controls complicated processes like movement, thought and memory. It also plays an essential role in the things your body does without thinking, such as breathing, blushing and blinking.

Detailed explanation-3: -The basic unit of the nervous system is the nerve cell (neuron). Nerve cells consist of a large cell body and two types of nerve fibers: Axon: A long, slender nerve fiber that projects from a nerve cell and can send messages as electrical impulses to other nerve cells and muscles.

Detailed explanation-4: -Biological psychology, also called physiological psychology, is the study of the biology of behavior; it focuses on the nervous system, hormones and genetics. Biological psychology examines the relationship between mind and body, neural mechanisms, and the influence of heredity on behavior.
