Exam 14: The Autonomic Nervous System

Thermoregulatory responses to increased heat are mediated by the sympathetic nervous division.

All splanchnic nerves are sympathetic.

The structures that specifically exhibit vasomotor tone are mostly under sympathetic control.

fi- adrenergic receptors are the only receptors found on the heart.

Sympathetic nerves may leave the spinal cord at which vertebra?

Cardiovascular effects of the sympathetic division include all except .

The division alone adapts the lens of the eye for close vision.

Figure 14.1Using Figure 14.1, match the following: -The only sympathetic preganglionic neuron to go directly to an organ is one branch of the splanchnic nerve.

Emotions influence autonomic reactions primarily through integration in the .

How are the sympathetic and parasympathetic divisions anatomically different?

The rami communicantes are associated only with the sympathetic division of the ANS.

The somatic and autonomic nervous systems differ in all of the following except .

The parasympathetic fibers of the nerves innervate smooth muscles of the eye that cause the lenses to bulge to accommodate close vision.

Sweat glands are innervated by the fibers alone.

Rami communicantes are designated white or grey to indicate whether or not the fibers passing through them are myelinated.

Preparing the body for the "fight- or- flight" response is the role of the .

The ANS stimulates smooth muscles, skeletal muscles and glands, whereas the somatic nervous system innervates skeletal muscles only.

The receptor type is used by the heart, and when activated increases heart rate.

Autonomic dysreflexia .

What effect does aging have on the ANS?
