The pain gate can theoretically reduce the sensation of pain sent by
A)unmyelinated axons only.
B)myelinated axons only.
C)both unmyelinated and myelinated axons.
D)neither unmyelinated nor myelinated axons.

Question

Quizplus · Accepted Answer

The pain gate theory proposes that certain nerve fibers carrying pain signals can be inhibited or blocked by input from other nerve fibers that carry non-painful signals. Both myelinated and unmyelinated fibers can transmit pain signals, so the pain gate can theoretically reduce the sensation of pain sent by both types of fibers.
