Function of meissner's corpuscles
WebSpecifically, the corpuscle is the nerve ending, or the tip of a very specialized peripheral axon. The Merkel's disk, however, is not a neuron. The neuro-peptides (called a neuro-peptide and not a neuro-transmitter because it's not released by a neuron) released are picked up by the afferent neurons and that trigger the action potential. 1 comment WebThey contain mechanically gated ion channels whose gates open or close in response to pressure, touch, stretching, and sound.” There are four primary tactile mechanoreceptors in human skin: Merkel’s disks, Meissner’s corpuscles, Ruffini endings, and Pacinian corpuscle; two are located toward the surface of the skin and two are located deeper.

This corpuscle is a type of nerve ending in the skin that is responsible for sensitivity to pressure.
