- Nervous system
- Central NS: brain and spinal cord
- Spinal cord can control reflex arcs (stimulus provokes an automatic response) without the help of the brain
- Serious injury can be perm
- Peripheral NS: all parts of NS outside brain and spinal cord - mostly nerves that can regrow - 2 parts
- axons of nerves outside brain and spinal cord and covered with neuriemma which forms a tunnel that damanged fibers can follow as they repair themselves
- Somatic NS : links spinal cord with body and sense organs - controls voluntary behavior
- Autonomic NS: carries info to and from internal organs and glands - controls automatic bodily processes
- Sympathetic: emergency system - arouses the body for action
- Parasympathetic: quiets the body down
- Central NS: brain and spinal cord
