The current record-holder for men, according to Guinness, is Shridhar Chillal from India who set the record in 1998 with a total of 20feet 2.25inches (615.32cm) of nails on his left hand. His longest nail, on his thumb, was 4feet 9.6inches (146.3cm) long.

The conditionas also called as nail atrophy, results in atrophy or wasting away of the plate thus making it lose its sheen. The body of nail gets smaller and in some cases, falls off completely. Onychatrophia can affect adults (men and women), infants and children, and toe as well as fingernails. Onychatrophia is not likely to cause discomfort or pain. This often occurs after an ailment or injury. In mammals, the growth rate of nails is related to the length of the terminal phalanges (outermost finger bones). Thus, in humans, the nail of the index finger grows faster than that of the little finger; and fingernails grow up to four times faster than toenails. [10] Finally, the nail functions as a tool enabling a so-called "extended precision grip" (e.g., pulling out a splinter in one's finger), and certain cutting or scraping actions. Practising good personal hygiene and taking proper care of hands and feet can help lower the risk of most problems affecting nail plates. Nail Plate PicturesThe nail is an unguis, meaning a keratin structure at the end of a digit. Other examples of ungues include the claw, hoof, and talon. The nails of primates and the hooves of running mammals evolved from the claws of earlier animals. [36] Maiolino, S.; Boyer, D.M.; Rosenberger, A. (2011).

In some cases, gel and cream cuticle removers can be used instead of cuticle scissors.

Fingernail Pathology

The nail consists of the nail plate, the nail matrix and the nail bed below it, and the grooves surrounding it. [2] Parts of the nail [ edit ] Wang, Bin (2016).

A study of the fingertip morphology of four small-bodied New World monkey species indicated a correlation between increasing small-branch foraging and: The best way to care for nails is to trim them regularly. Filing is also recommended, as to keep nails from becoming too rough and to remove any small bumps or ridges that may cause the nail to get tangled up in materials such as cloth.

With only a few exceptions, primates retain plesiomorphic (original, "primitive") hands with five digits, each equipped with either a nail or a claw. For example, nearly all living strepsirrhine primates have nails on all digits except the second toe which is equipped with a grooming claw. Tarsiers have a grooming claw on second and third toes. Less commonly known, a grooming claw is also found on the second pedal digit of owl monkeys ( Aotus), titis ( Callicebus), and possibly other New World monkeys. [37] The needle-clawed bushbaby ( Euoticus) has keeled nails (the thumb and the first and the second toes have claws) featuring a central ridge that ends in a needle-like tip.

The nail bed is the skin beneath the nail plate. It is the area of the nail on which the nail plate rests. Nerves and blood vessels found here supply nourishment to the entire nail unit. Like all skin, it is made of two types of tissues: the dermis and the epidermis. The epidermis is attached to the dermis by tiny longitudinal "grooves" called matrix crests ( cristae matricis unguis). [3] In old age, the nail plate becomes thinner, and these grooves become more visible. [ citation needed] The nail bed is highly innervated, and removal of the nail plate is often excruciatingly painful as a result. [ citation needed] Inherited accessory nail of the fifth toe occurs where the toenail of the smallest toe is separated, forming a smaller "sixth toenail" in the outer corner of the nail. [23] Like any other nail, it can be cut using a nail clipper. The nail wall ( vallum unguis) is the cutaneous fold overlapping the sides and proximal end of the nail. The lateral margin ( margo lateralis) lies beneath the nail wall on the sides of the nail, and the nail groove or fold ( sulcus matricis unguis) are the cutaneous slits into which the lateral margins are embedded.

A healthy fingernail has the function of protecting the distal phalanx, the fingertip, and the surrounding soft tissues from injuries. It also serves to enhance precise delicate movements of the distal digits through counter-pressure exerted on the pulp of the finger. [2] a b K. A. Walters and G. L.
