1. ____________________________
Nervous system subdivision that is composed of the
brain and spinal cord.
2. ____________________________
Subdivision of the PNS tat controls voluntary
activities such as the activation of skeletal muscles.
3. ____________________________
Nervous system subdivision that is composed of the
cranial and spinal nerves and ganglia.

-
- detect stimuli
neurons are also called _________________________
- integrates sensory information by analyzing and storing, making
decisions
neurons are also called __________________________ and are most of the
neurons in the body
- respond to stimuli
neurons are also called ___________________________ which carry information
out of the brain and spinal cord
