Exam 9: The Autonomic Nervous System

Organs innervated by autonomic motor neurons are often under voluntary control.

Damage to the gray rami communicantes would inhibit the parasympathetic division of the autonomic nervous system.

Stimulation of the iris by parasympathetic nerves stimulates pupillary constriction.

The swellings on postganglionic axons that contain neurotransmitter are called

Many autonomic visceral effector organs can function without nervous innervation.

The splanchnic nerves synapse in the

Postganglionic sympathetic neurons arise from the thoracic and lumbar regions of the spinal cord.

Four of the twelve pairs of cranial nerves give rise to parasympathetic preganglionic nerves.

Visceral reactions which accompany emotional states are due to activation of the autonomic nervous system by the
