What area of the body does the phrenic nerve innervate

true

Motor neurons travel out of the anterior root of the spinal nerve(T/F)

conus medullaris

What is the tapered end of the spinal cord called

False

The anterior white column is an ascending tract that carries motor commands to the brain from the periphery (T/F)

cauda equina

Which part of the spinal cord has nerve roots that resembles a horse's tail

true

The white matter of the spinal cord is compromised of myelinated axons that extend to and from the brain ( T/F)

True

The spinal cord is considered part of the central nervous system while the spinal nerves are considered part of the peripheral nervous system.

dorsal gray horn

receiving and relaying sensory info from spinal nerves

somatic sensory nuclei

receive and relay information from joints and skin

visceral sensory nuclei

recieve info from organs

lateral gray horn

Location of visceral motor nuclei which communicate with smooth and cardiac muscle

(Pink line)

Subarachnoid space which contain cerebralspinal fluid.

What’s the line indicating and what dose is contain?
