Exam 19: The Autonomic Nervous System

List the four cranial nerves that carry parasympathetic motor impulses. Three pairs of these nerves lead to four pairs of ganglia. Name the ganglia and state which cranial nerves connect to them.

Select the best description of the pterygopalatine ganglia:

Which division of the autonomic nervous system is responsible for preparing the body for an emergency situation? Describe the responses of the body that collectively are referred to as the fight-or-flight response.

Spinal nerve C4 receives postganglionic sympathetic axons (fibers) from:

The lateral gray horns of the thoracic region contain cell bodies of _____ (sympathetic or parasympathetic) preganglionic neurons.

The hypothalamus is the major control and integration center of the autonomic nervous system.

Nicotinic receptors and muscarinic receptors both interact with acetylcholine (ACh).

White rami are associated only with thoracic spinal nerves and the first two or three lumbar spinal nerves. Gray rami are associated with all 31 pairs of spinal nerves.

Which of the following is/are innervated ONLY by the sympathetic division? 1) arrector pili muscles 2) kidney arterioles 3) sweat glands 4) adipose tissue 5) skeletal muscle arterioles 6) brain arterioles 7) adrenal medulla

There are two main types of receptors for both acetylcholine (ACh) and for norepinephrine (NE). Give the names of the receptors, the general location of each, and the expected effect of stimulation of each receptor type.

Select the best description of a white ramus:

Select the best description of the parasympathetic preganglionic neurons:

Autonomic innervation (stimulation) from the _____ division results in vasoconstriction of blood vessels in the dermis of the skin.

The _____ is the major control and integration center of the autonomic nervous system.

All adrenergic alpha receptors are ALWAYS excitatory.
