Select the statement that explains the neural mechanism underlying the sensation of fast, sharp pain followed by delayed, longer-lasting pain after an injury.
a. Fast pain is conducted by mechanoreceptors, whereas delayed pain is conducted by fibers with free nerve endings.
b. Fast pain is conducted by free nerve endings in the dermis, whereas delayed pain is conducted by deep nerve endings in the subcutaneous layer.
c. The receptive fields differ for the two types of pain sensation such that fast pain fibers have smaller receptive fields than the delayed pain fibers.
d. Fast and delayed pain represent the progression of the injury; both are conducted by the same fibers.
e. Fast, sharp pain is conducted by myelinated axons, whereas delayed, longer-lasting pain is carried by unmyelinated axons.

A. True
B. False
The eye doctor uses an Acetylcholine-receptor blocker to maximally dilate the
pupils; this allows the doctor to peer deep into the posterior eye-ball and observe
the retina. Considering these facts, which nervous system is usually controlling the
pupil diameter? (Which nervous system is “Acetylcholinergic"?)
a. Somatosensory nervous system
b. Sympathetic nervous system
c. Reticular attenuating nervous system
d. Parasympathetic nervous system
