WebHistologically, a Pacini corpuscle consists of a central axon (see Fig. 2-1 A and B) surrounded by layers of perineurial lamellae, which create a distinguishing capsule (see Fig. 2-1 C). In the ligament, this receptor is quite small with a diameter of 20 to 50 μm. The Pacini corpuscle in the skin and the palm of the hand is highly sensitive to ... Web21 nov. 2024 · D. TCLBs (formerly known as Wagner-Meissner corpuscles) are Schwannian mechanoreceptors found primarily in the skin and not normally present in the gastrointestinal tract (GIT).
