Reflection Prompt: What is a peripheral nervous system? How is it different from the central nervous system?

What is the central nervous system? The cen______ nervous system is the control center of the body. It includes the brain and the spi____ cord. nal

The Brain The three main regions of the brain are the cerebr____, the cerebell___ and the brain stem. um um

The Cerebrum Cerebrum is the largest part of the brain. The cerebrum interprets input from the senses, controls move_____, and carries out learning and remem______ ment bering

The Cerebellum and Brain Stem The cerebellum coordinates muscle action and bal_____ The brain stem controls brea_____and heartbeat ance thing

What is the peripheral nervous system? The peripheral nervous system includes all the nerves located outside of the cen____ nervous system. The peripheral nervous system is involved in both involuntary and volun_____ actions. tral tary

Somatic and Autonomic Nervous System Peripheral nervous system is divided into som_____ and auto________ nervous system Somatic nervous system control voluntary actions (picking up a fork) Autonomic nervous system controls involuntary actions (breathing) atic nomic

Reflex Action When you touch a hot object, the nerve impulses travel the spi_____ cord . The spinal cord tells the motor neur_____ to pull your hand away. As you pull your hand away, nerve impulses travel to the brain and you feel the pain. nal ons

Concussion A concussion is a bruise like injury of the brain. After a concussion, you may have a head_____ for short time. With more serious concussion, you may lose con___________, experience confusion, or feel drowsy. ache sciousness
