Describe briefly the structure of the finger nail eg;nail plate,nail bed,matrix,cuticle,lunula,ect?

Well, u have the whole list. What do u wana know?


The nail bed is the skin at the tip of ur finger on which the nail grows; the plate is the nail itself.


The cuticle is the skin round the nail that holds the root of the nail plate and the sides as well.


i don't know what matrix and lunula are, but there's a nail crescent which is the white colour that sometimes appears at the base of ur nail.


I'm not sure but i think the matrix will be the whole finger tip that houses the nail.


Yea, that's as far as i know. Good luck.Describe briefly the structure of the finger nail eg;nail plate,nail bed,matrix,cuticle,lunula,ect?
Fingernails and toenails, which are made of protein and are a form of modified hair, are composed of:





the nail matrix or the root of the nail - this is the growing part of the nail still under the skin at the nail's proximal end.


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


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


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


nail plate which is what we think of when we say nail, the hard and translucent portion, composed of keratin.


nail bed which is the adherent connective tissue that underlies the nail.


lunula which is the crescent shaped whitish area of the nail bed.


Nails grow at an average rate of 0.1 mm/day (1 cm every 100 days).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
