Peripheral nervous system is a collection of nerve fibers and cell bodies outside the ….made up of either ….or ….nerves.

A

CNS, spinal or cranial

10
Q

Peripheral nerves carry information to….or control movements and functions from the brain and spinal cord to the body.

A

spinal cord or brain

11
Q

Somatic motor nerve cell body of spinal nerve lies in the ….of the spinal cord while it sends information through the axon to …muscle as far as a meter away.

A

ventral horn, innervate

12
Q

somatic sensory nerve cell body resides in the ….receiving information via axon from the skin and synapsing on nerves in ….of the spinal cord.

A

dorsal root ganglia, dorsal horn

13
Q

rhizotomy

A

sectioning of the dorsal or ventral roots of a spinal nerve in order to relive intractable pain or spastic paralysis.

14
Q

ANS

A

visceral motor system that modulates internal organ function

15
