How do finger and toe nails grow?

nails are part of the skin, and grow from a protein called keratin, which is produced by cells under the surface of your skin, at the root (white part of your nail.)How do finger and toe nails grow?
dunoHow do finger and toe nails grow?
they grow from the base, out of the cuticle.
They are produced from the skin and are primarily to protect the tips and tops of the fingers and toes from scrapes and crush type injuries.

Not sure about the finger nails as mine seem to break constantly but the toe nails grow quite nicely given the fact that I need to cut them.





Its a pity its not visa versa lol.
quite slowly
From the base of the cuticle.I think...I know mine grow slowly...darn it!!!Too much manual labor and hand washing!
They are dead skin cells apparently and the finger nails grow 10 times faster than the toe nails (no idea why).
Anatomically fingernails and toenails, which are made of a tough protein called keratin and are produced from living skin cells in the fingers and toes, are made up of many different parts:





The free edge is the part of the nail that extends past the finger, beyond the nail plate. There are no nerve endings in the nail - this is the growing part of the nail still under the skin at the nail's proximal end.


eponychium or cuticle, is the fold of skin at the proximal end of the nail.


paronychium is the fold of skin on the sides of the nail.


hyponychium is the attachment between the skin of the finger or toe and the distal end of the nail.


nail plate is the hard and translucent portion, composed of keratin.


nail bed is the adherent connective tissue that underlies the nail, often colloquially referred to as the ';quick.';


lunula is the crescent shaped whitish area of the nail bed (when visible)


nail fold a fold of hard skin overlapping the base and sides of a fingernail or toenail.


In common usage the word nail usually refers to the nail plate only.

















Long, manicured nails are a fashion statement.Nails grow at an average rate of 3 millimetres a month [1] Fingernails require 3 to 6 months to regrow completely. Toenails require 12 to 18 months. Actual growth rate is dependent upon age, season, exercise level, and hereditary factors. Contrary to popular belief, nails do not continue to grow after death; the skin dehydrates and tightens, making the nails (and hair) appear to grow.





This growth record can show the history of recent health and physiological imbalances, and has been used as a diagnostic tool since ancient times.[2] Major illness will cause a deep groove to form across the nails. Discoloration, thinning, thickening, brittleness, splitting, grooves, Mees' lines, small white spots, receded lunula, clubbing (convex), flatness, spooning (concave) can indicate illness in other areas of the body, nutrient deficiencies, drug reaction or poisoning, or merely local injury. Nails can also become thickened (onychogryphosis), loosened (onycholysis), infected with fungus (onychomycosis) or degenerative (onychodystrophy); for further information see nail diseases.
appartently they are by products, or waste products from your body, thats all I know and thats how they can tell if you have calcium deficencies, it show in your nails. I know this isnt that helpful but its better than nothing
they come out of ur fingers and toes...
Wow Quiz! Can't beat that awesomely thorough answer! Well done!

It doesn't actually grow at the white end- it grow right in where your skin meets your nail. Then, when it has grown enough to reach the white bit it turns white then you cut it off. Hope that helped!
