Merkel cells (shown in blue) are located in the basal epidermal layer of the skin. Merkel cells, also known as Merkel–Ranvier cells or tactile epithelial cells, are oval-shaped mechanoreceptors essential for light touch sensation and found in the skin of vertebrates. They are abundant in highly sensitive skin like that of the fingertips in ...
The glabrous skin on the sole of the foot lacks the hair and pigmentation found elsewhere on the body, and it has a high concentration of sweat pores. The sole contains the thickest layers of skin on the body due to the weight that is continually placed on it. It is crossed by a set of creases that form during the early stages of embryonic ...

Merkel nerve endings are extremely sensitive to tissue displacement, and may respond to displacements of less than 1 μm. A mechanoreceptor's receptive field is the area within which a stimulus can excite the cell. If the skin is touched in two separate points within a single receptive field, the person will be unable to feel the two separate ...
Cuboid syndrome. Cuboid syndrome or cuboid subluxation describes a condition that results from subtle injury to the calcaneocuboid joint, [ 1] and ligaments in the vicinity of the cuboid bone, one of seven tarsal bones of the human foot .

Corn (pathology) A corn or clavus (plural clavi or clavuses) is an often painful, cone-shaped, inwardly directed callus of dead skin that forms at a pressure point near a bone, or on a weight-bearing part of the body.
