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 ...
Onychorrhexis also known as brittle nails, is brittleness with breakage of fingernails or toenails. Paronychia is a bacterial or fungal infection where the nail and skin meet. Koilonychia is when the nail curves upwards (becomes spoon-shaped) due to an iron deficiency. The normal process of change is: brittle nails, straight nails, spoon-shaped ...

Guinness World Records began tracking record fingernail lengths in 1955, when a Chinese priest was listed as having fingernails 1 foot 10.75 inches (57.79 cm) long. The current record-holder for men, according to Guinness , is Shridhar Chillal from India who set the record in 1998 with a total of 20 feet 2.25 inches (615.32 cm) of nails on his ...
Removed nails are capable of growing back normally over several months if the nail matrix is left intact through surgical extraction. However, if the matrix is damaged by trauma, it can result in an overgrowth of tissue from the proximal nail fold, resulting in the formation of pterygium. Particularly, if the nail matrix is burnt by a heated ...
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).
DNA from an unidentified male was found under Maggie Murdaugh’s fingernails, SLED forensic scientist Sarah Zapata said under cross-examination. Paul and Alex Murdaugh were excluded as ...
While ingrown nails can occur in the nails of both the hands and the feet, they occur most commonly with the toenails (as opposed to fingernails). [citation needed] A common misconception is that the cause of an ingrown toenail is the nail growing into the paronychium, but it can also be caused by overgrown toe skin. [2]
