Question 1

Which statement is true regarding the spinal nerve and cord?

Answers:            

As a spinal nerve approaches the spinal cord, it separates into lateral and medial roots

 Spinal nerves exit the spinal cord through the intervertebral foramen of the vertebrae

The dorsal root of the spinal nerves transmit (carry) information from the central nervous system out to the body

A spinal nerve a single sensory axon and single motor axon

Question 2

Which choice is true regarding the brain stem?

Answers:            

 The midbrain contains visual and auditory reflex centers

One of the pons functions is to control behavior and emotion.
