Detailed explanation-1: -The visceral (or autonomic) motor system controls involuntary functions mediated by the activity of smooth muscle fibers, cardiac muscle fibers, and glands.
Detailed explanation-2: -Visceral efferent neurons are motor neurons that conduct impulses to smooth muscle, cardiac muscle, & glands. These neurons make up the Autonomic Nervous System. Some visceral efferent neurons begin in the brain; others in the spinal cord.
Detailed explanation-3: -Autonomic motor neurons innervate smooth and cardiac muscle, glands, and visceral organs.
Detailed explanation-4: -The ANS is not under conscious control, with visceral motor neurons stimulating all peripheral effectors except for skeletal muscles. They innervate cardiac and smooth muscle, adipose tissue, and glands. Visceral motor axons in the CNS innervate other visceral motor neurons in the peripheral autonomic ganglia.
