MUSCLE PHYSIOLOGY

Detailed explanation-1: -Merkel’s disks are densely distributed in the fingertips and lips. They are slow-adapting, unencapsulated nerve endings, which respond to light touch.

Detailed explanation-2: -Selective stimulation of these receptors in humans produces a sensation of light pressure. These several properties have led to the supposition that Merkel’s disks play a major role in the static discrimination of shapes, edges, and rough textures.

Detailed explanation-3: -Slowly adapting, encapsulated Merkel’s disks are found in fingertips and lips, and respond to light touch. Meissner’s corpuscles, found in glabrous skin, are rapidly adapting, encapsulated receptors that detect touch, low-frequency vibration, and flutter.

Detailed explanation-4: -A mechanoreceptor is a sensory receptor that responds to mechanical pressure or distortion. Normally, there are four main types in glabrous skin: Pacinian corpuscles, Meissner’s corpuscles, Merkel’s discs and Ruffini endings.
