Exam 15: Nervous System: Autonomic Nervous System

Dual innervation means that an individual effector

Catecholamines include

The circuitry of the autonomic system allows for control in activation. The characteristic that allows a small number of preganglionic cells to stimulate a large number of postganglionic cells is

Typically, alpha adrenergic receptors have

The centers for cardiac, digestive, and vasomotor functions are housed within the

The ________ division of the ANS is most commonly associated with the preparation of the body for emergencies.

The sympathetic trunk ganglia are primarily composed of

When norepinephrine is released from postganglionic neurons, its targets are

Parasympathetic activity is responsible for increased smooth muscle motility and secretory activity in digestive tract organs.

Which autonomic plexus innervates viscera within the pelvic region?

Activation of parasympathetic fibers in pelvic splanchnic nerves leads to

The diameter of many blood vessels is controlled exclusively by the ________ nervous system, and decreases in the activity of this system result in ________.

The ________ ganglia differ from the sympathetic trunk ganglia segments in that they are single structures, rather than paired.

The type of adrenergic receptor found on the smooth muscle cells of blood vessels in the skin is

With respect to divergence of axons in the sympathetic division of the ANS, one axon innervates fewer than four ganglionic cell bodies.

The sympathetic division pathway that results in innervation of the pelvic organs has its spinal cord segment origin in

Except for the ________ region of the spinal cord, one sympathetic trunk ganglion is approximately associated with each spinal nerve.

Gray rami from the sympathetic trunk connect to

Sweat glands and arrector pili muscles are controlled

The parasympathetic postganglionic axons that travel to the pupillary constrictor muscle result in pupil ________ when the eye is exposed to bright light.
