Made up of peripheral nerves that connects the cns to the body"s receptors and effectors. Made up of the brain and spinal cord. Consists of an autonomic system involved in the cns and a somatic system. Controls outside functions: movement, reflex, lung inhalation, heartbeat, etc. Autonomic system: controls self-regulated action of internal glands, split into two sections. Somatic system: controls voluntary movements of skeletal, cerebellum (houses 70 billion neurons, cerebral cortex (houses. Brain has to categories: cortical (outer area of the brain that controls higher functions of life learning, sub-cortical (section below cortex that controls more primitive/survival functions)
