Question 2

The primary integrating center of the ANS is the ________ of the diencephalon.

Accepted Answer

hypothalamus

Question 3

The sympathetic and parasympathetic divisions differ markedly in the branching of the postganglionic fibers. Explain the anatomical difference and its significance.

Accepted Answer

The postganglionic fibers of the parasympathetic division are short and often enclosed within the tissues they innervate. In contrast, the postganglionic sympathetic fibers are highly branched and innervate multiple tissues; nerve impulses from one fiber will simultaneously activate multiple target tissues. The simultaneous activation of wide-ranging tissues and organs is necessary for a fight-or-flight response.
