The hyponychium (IPA: / ˌ h aɪ p oʊ ˈ n ɪ k i ə m /) [1] [2] is the area of epithelium, particularly the thickened portion, underlying the free edge of the nail plate on the nail. Its proximal border is immediately distal to distal limit of nail bed—a.k.a. the onychodermal band (the line along the interface of the nail bed and the nail ...
sweat gland. Skin secretions are those substances and materials that are secreted by the skin and the external mucous membranes.Some skin secretions are associated with body hair.
In human anatomy, the eponychium is the thickened layer of skin at the base of the fingernails and toenails. [1] It can also be called the medial or proximal nail fold. Its function is to protect the area between the nail and epidermis from exposure to bacteria.
The lunula is located at the end of the nail that is closest to the skin of the finger, but it still lies under the nail. It is not actually white but only appears so when it is seen through the nail. Outlining the nail matrix, the lunula is a very delicate part of the nail structure. If one damages the lunula, the nail will be permanently ...
An ingrown nail, also known as onychocryptosis (from Greek: ὄνυξ (onyx) 'nail' and κρυπτός (kryptos) 'hidden') is a common form of nail disease.It is an often painful condition in which the nail grows so that it cuts into one or both sides of the paronychium or nail bed.
The integumentary system includes skin, hair, scales, feathers, hooves, claws, and nails. It has a variety of additional functions: it may serve to maintain water balance, protect the deeper tissues, excrete wastes, and regulate body temperature , and is the attachment site for sensory receptors which detect pain, sensation, pressure, and ...
Some publications propose shortening the nail bed to the end of the bony support if it continues past the limit of the severed distal phalanx in order to prevent deformity. [4] Treatments intended to preserve length, such as replantation or flap reconstruction, should be used if the damage to the bone and soft tissue beneath the nail bed is too ...
In humans, some of the more common skin appendages are hairs (sensation, heat loss, filter for breathing, protection), arrector pilli (smooth muscles that pull hairs straight), sebaceous glands (secrete sebum onto hair follicle, which oils the hair), sweat glands (can secrete sweat with strong odour or with a faint odour (merocrine or eccrine ...
