True
7) The sympathetic chain is composed of collateral ganglia.
True
8) Thermoregulatory responses to increased heat are mediated by the sympathetic nervous division.
True
9) Most disorders of the autonomic nervous system reflect abnormalities of smooth muscle control.
True
18) The parasympathetic division is a branch of the somatic nervous system.
False
13) Most body organs are innervated by only the sympathetic division of the nervous system.

1) Since the ANS is a visceral motor system, afferent pathways are of no importance and actually are rarely found.
False
17) Norepinephrine-releasing fibers are called cholinergic fibers.
False
20) The chain ganglion, like the dorsal root ganglion, contains soma from sensory neurons.

22) The blood vessels of the skin are one of the few areas of the body where the vessels are innervated by both the sympathetic and parasympathetic divisions.
False
24) All splanchnic nerves are sympathetic.
False
27) Since many of the same cardiac cells are innervated by both parasympathetic and sympathetic fibers, the influence of the two divisions on the heart is synergistic.
False
28) β-adrenergic receptors are the only receptors found on the heart.
False
