tactile meniscus
meniscus tactus one of the small, cup-shaped, tactile nerve endings within the skin; many of them are formed by branches of a single nerve fiber, and each one is in contact with a single, modified epithelial cell called a Merkel cell. These are found in the deep epidermis, in hair follicles, and in the hard palate, and function as tactile receptors. Called also tactile disk.
