Vocabulary Central nervous system- consists of brain and spinal cord Peripheral nervous system- consists of all the nerves located outside the nervous system

Central Nervous System Is the control center of the body and includes the brain and the spinal cord Three main regions of the brain: the cerebrum, cerebellum, and the brain stem.

Vocabulary Cerebrum- interprets input from the senses, controls movements, and carries out complex mental processes such as learning and remembering. Cerebellum- coordinates the actions of your muscles and helps you keep your balance Brain stem- controls your body’s involuntarys actions.

Peripheral Nervous System Consists of a network of nerves that branch out from the central nervous system and connect to the rest of the body. This nervous system is involved in various actions both voluntary and involuntary.

Peripheral Nervous System The nerves of the peripheral nervous system can be divided into somatic and autonomic nervous stem. Somatic- controls voluntary actions or what you control. Autonomic- controls involuntary actions like your heart beating.

Vocabulary Reflex-an automatic response that occur vary rapidly and without conscience control. Reflexes help protect the body Concussion-A bruise-like injury to the brain Concussions and spinal cord injuries are two ways in which the nervous system can be damaged
