Question

Quizplus · Accepted Answer

The description matches that of a tactile (Merkel) disc, which is a highly sensitive tactile receptor composed of dendritic processes of a single myelinated fiber that makes contact with specialized cells of the stratum germinativum (basale). Lamellated corpuscles, Ruffini corpuscles, and root hair plexuses are all types of tactile receptors, but their descriptions do not match the given information as closely as a Merkel disc. Meissner corpuscles are also tactile receptors, but they consist of specialized cells rather than dendritic processes.
