MUSCLE PHYSIOLOGY

Detailed explanation-1: -Meissner’s corpuscles, found in glabrous skin, are rapidly adapting, encapsulated receptors that detect touch, low-frequency vibration, and flutter. Ruffini endings are slowly adapting, encapsulated receptors that detect skin stretch, joint activity, and warmth.

Detailed explanation-2: -The two most numerous types of mechanosensory corpuscles in the human palm are Pacinian and Meissner corpuscles. Pacinian corpuscles detect high-frequency vibration, whereas Meissner are tuned to lower frequencies (2, 5, 9). Both types are innervated by myelinated mechanoreceptors that arise from somatosensory ganglia.
