Meissner's corpuscles

Japanese: マイスネル小体 - マイスネルしょうたい（英語表記）Meissner’s corpuscle

A specialized sensory nerve ending located in the superficial layer of the skin of the palms and soles, near the boundary between the epidermis and dermis. It is about 0.08 mm x 0.5 mm in size and senses touch. It is also called a tactile corpuscle. The main components of this corpuscle are the peripheral parts of myelinated AII type fibers, which are among the thicker of the sensory nerve fibers distributed in the skin, and a group of lamellar cells surrounding them in 5 to 10 layers. Within the corpuscle, the nerve fibers become unmyelinated and repeatedly meander and branch, but are always densely covered by lamellar cells.

手掌や足底の皮膚の浅層，すなわち表皮と真皮の境界部付近にある知覚神経の特殊終末装置。0.08mm×0.5mmほどの大きさで触覚を感受するもので，触覚小体ともよばれる。皮膚に分布する知覚神経繊維のうちでも太いほうに属する有髄性のAII型繊維の末梢部分と，これを5～10層に囲む層板状細胞群とが，この小体の主要構成要素である。神経繊維は，小体内で無髄化し，蛇行と分枝をくり返すが，層板状細胞による密な覆いをつねに受けている。
