Sharp, localized (fast)pain is rapidly transmitted to the central nervous system along
A) large, unmyelinated C fibers.
B) small, myelinated A-delta fibers.
C) small, unmyelinated C fibers.
D) large, myelinated A-beta fibers.

Question

Quizplus · Accepted Answer

Small, myelinated A-delta fibers are responsible for the rapid transmission of sharp, localized pain to the central nervous system. They have a faster conduction velocity than the unmyelinated C fibers, which transmit dull, aching pain. The large, myelinated A-beta fibers are responsible for touch and light pressure sensation.
