Question

Quizplus · Accepted Answer

The description matches that of a lamellated corpuscle, which is a fast-adapting tactile receptor composed of a single dendrite enclosed by concentric layers of collagen. Ruffini corpuscles have elongated and branched dendrites, tactile (Meissner) corpuscles have a stack of flattened cells around the dendrite, tactile (Merkel) discs have flattened cells around the dendrite, and root hair plexus are a network of nerves around hair follicles.
