Labelled pacinian corpuscle
WebLamellar corpuscles, or Pacinian corpuscles or Golgi-Mazzoni corpuscles , are one of the four major types of mechanoreceptor. They are nerve endings in the skin responsible for sensitivity to vibration and pressure. Vibrational role may be used to detect surface, e.g., rough vs. smooth.

WebMar 6, 2024 · Meissner corpuscles, also known as Wagner-Meissner corpuscles or tactile corpuscles, are a subset of mechanoreceptors first described by Professor Georg Meissner and Professor Rudolf Wagner in 1852. WebPacinian corpuscles (seen in Figure 4) are located deep in the dermis of both glabrous and hairy skin and are structurally similar to Meissner’s corpuscles; they are found in the bone periosteum, joint capsules, …
WebDec 13, 2024 · Pacinian corpuscles, also known as Vater-Pacini corpuscles or lamellar corpuscles, are pressure-sensitive nerve endings in the skin. They are the largest mechanoreceptors in the body and are important to recognize as they may be mistaken for pathology. Gross anatomy 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.
