A nail is a protective plate characteristically found at the tip of the digits (fingers and toes) of all primates, corresponding to the claws in other tetrapod animals. . Fingernails and toenails are made of a tough rigid protein called alpha-keratin, a polymer also found in the claws, hooves, and horns of ver
The lunula (pl.: lunulae; from Latin 'little moon') is the crescent-shaped whitish area of the bed of a fingernail or toenail. In humans, it appears by week 14 [1] of gestation, and has a primary structural role in defining the free edge of the distal nail plate (the part of the nail that grows outward).
Anatomy of the basic parts of a human nail.A. Nail plate; B. lunula; C. root; D. sinus; E. matrix; F. nail bed; G. eponychium; H. free margin. Onychia is an inflammation of the nail folds (surrounding tissue of the nail plate) of the nail with formation of pus and shedding of the nail.
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. The eponychium differs from the cuticle; the eponychium comprises live skin cells whilst the cuticle is dead skin cells.
Pale white nails If your fingernail beds are looking a little ghostly, you may have anemia due to low levels of iron. This could lead to low levels of oxygen, which causes the skin and tissues to ...
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 ...
Anatomy of the basic parts of a human nail. In human anatomy, "cuticle" can refer to several structures, but it is used in general parlance, and even by medical professionals, to refer to the thickened layer of skin surrounding fingernails and toenails (the eponychium), and to refer to the superficial layer of overlapping cells covering the hair shaft (cuticula pili), consisting of dead cells ...
