A) A$\alpha$
B) A$\beta$
C) A$\delta$
D) C

Question

Quizplus · Accepted Answer

Meissner's corpuscles, Pacinian corpuscles, Merkel's disks, and Rufinni endings are all types of specialized nerve endings in the skin responsible for detecting different types of sensory information. They are all served by A beta (AF) fibers, which are medium-sized myelinated nerve fibers that transmit signals quickly and accurately. Among the available choices, only option B includes AF fibers, specifically AF1, AF2, and AF10, which are known to serve these four types of sensory receptors. Option C includes C fibers, which are unmyelinated and slower than AF fibers, and options A and D do not include AF fibers at all. Therefore, option B is the best choice.
