2 points

A. A cranial nerve is part of the CAN and is an extension of only the cerebrum of the brain; a spinal nerve is a part of the PNS and emanates from the spinal column

B. A cranial nerve is a part of the PNS and emanates from the brainstem brain and cerebrum; a spinal nerve is a part of the PNS and emanates from the spinal column

C. A cranial nerve is part of the CNS and emanates from the cerebrum only; a spinal nerve is a part of the PNS and emanates from the brainstem

D. A cranial nerve is part of the PNS and emanates from the spinal cord ventral to the brain; a spinal nerve is a part of the PNA and emanates from the brainstem

Explanation / Answer

Answer:

B. A cranial nerve is a part of the PNS and emanates from the brainstem brain and cerebrum; a spinal nerve is a part of the PNS and emanates from the spinal column.
