Merkel Disc

So it kinda sits in your epidermis. That is the hairless skin found on the palms and fingers the soles of the feet and the lips of humans and other primates. The disklike expansion of the end of a nerve fiber together with a closely associated merkel cell that has a presumed tactile function called also merkels corpuscle learn more about merkels disk.

Merkel cells in the basal epidermis of the skin store serotonin which they release to associated nerve endings in response to pressure.

Merkel disc. The information they provide are those regarding pressure and texture. Each ending consists of a merkel cell in close apposition with an enlarged nerve terminal. Merkel nerve endings are mechanoreceptors found in the skin and mucosa of vertebrates that provide touch information to the brain. The merkel disc has high tactile acuity for an objects physical features such as texture shape and edges.

Merkels disks are densely distributed in the fingertips and lips. Merkels disks are found in the upper layers of skin near the base of the epidermis both in skin that has hair and on glabrous skin. Anatomist 18451919 the tiny expanded end of a sensory nerve fiber found in the epidermis and in the epithelial root sheath of a hair. The merkel disc a main type of tactile end organ consisting of merkel cells mcs and ab afferent endings are highly abundant in fingertips touch domes and whisker hair follicles of mammals.

The merkel disc a main type of tactile end organ consisting of merkel cells mcs and ab afferent endings are highly abundant in fingertips touch domes and whisker hair fol licles of mammals. Merkel disks are mechanoreceptors in the skin beneath the epidermis which are sensitive but also slowly adapting and are found in particularly high concentration in skin on the outer extremities the lips and on the outer genitials. This also has an afferent nerve fiber that sits right there. And thats because merkels disk is actually just a specialized keratinocyte or an epithelial cell thats not unlike the regular cells you have in your epidermis.

So it kinda looks like this. The merkel disc has high tactile acuity for an objects physical features such as texture shape and edges. This is sometimes referred to as a merkel cellneurite complex or a merkel disc receptor. Each ending consists of a merkel cell in close apposition with an enlarged nerve terminal.
