Answer 1

Differences
Voluntary motor system that innervate the head	Voluntary motor system that innervate the body
The stimulus from precentral gyrus is transmitted from upper motor neurons and down the corticospinal tract.	It leads to depolarization and prolongation of action potential
Cranial nerves carry information from and towards the brain stem.	Spinal Nerves carry sensory information towards the commands out of the spinal cord.

Similarity
Voluntary motor system that innervate the head	Voluntary motor system that innervate the body
The key function of somatic nervous system is to associate the central nervous system with the muscles of the body and regulates the voluntary movements along with reflex arc.
