Tactile corpuscles exist in encapsulated myelinated nerve endings, enveloped by Schwann cells.
Tactile corpuscles exist in encapsulated myelinated nerve endings, enveloped by Schwann cells. The encapsulation consists of flattened supporting cells set as horizontal lamellae encircled by a connective tissue capsule. The corpuscle exists 30–140 μm in length and 40–60 μm in diameter.
