默克爾神經末梢

默克爾神經末梢（英文：Merkel nerve ending），又稱默克爾觸覺盤（Merkel's tactile disk）或默克爾盤（Merkel's disk），是一種緩慢調節的力學感受器，位於表皮基底層與毛囊中^[1]^[2]^[3]。默克爾神經末梢以德國科學家弗里德里希·西格蒙德·默克爾的名字命名。它們能感知機械壓力和位置，也能通過深層靜態觸碰進行特徵感知，譬如感知形狀和邊緣^[1]。

默克爾細胞位於表皮基底層，儲存血清素，並在感知壓力時釋放至相應的神經末梢^[3]^[4]。每個末梢都由一個默克爾細胞與一個鄰近神經終端的組成，因此被稱為「默克爾細胞-神經突複合體（Merkel cell–neurite complex）」或默克爾觸覺盤^[1]^[5]。單個傳入神經纖維可支配約90個此種神經末梢。
