| nail matrix | The area of the corium on which the nail rests; it is extremely sensitive and presents numerous longitudinal ridges on its surface. According to some anatomists, the nail bed is the portion covered by the body of the nail, the nail matrix being only the part on which the root of the nail rests.

| nail-patella syndrome | <radiology> Fong syndrome, hereditary arthrodysplasia, J.W. Turner syndrome, autosomal dominant Features: abnormal fingernails, absent/hypoplastic patella, defects in radial head, iliac horns (bony processes along posterior surfaces of iliac bones), discoloration of iris (12 Dec 1998) |
| nail pits | Small punctate depressions on the surface of the nail plate due to defective nail formation; seen in psoriasis and other disorders. See: geographic stippling of nails. (05 Mar 2000) |
| nail pulse | A capillary pulse seen through the nail. (05 Mar 2000) |
| syndrome, nail-patella | Hereditary dominant condition with abnormally formed (dysplastic) or absent nails and absent or underdeveloped (hypoplastic) kneecaps (patellae). Other features include iliac horns (symmetrical bilateral central posterior iliac processes), abnormality of the elbows interfering with full range of motion (pronation and supination) and kidney disease resembling glomerulonephritis which.is often mild but can be progressive and lead to renal failure. The nail-patella gene locus found linked genetically to the abo blood group in1965 is now known to be in chromosome region 9q34. Also called onychoosteodysplasia, turner-kieser syndrome, and fong disease. (12 Dec 1998) |
| ingrown nail | A toenail, one edge of which is overgrown by the nailfold, producing a pyogenic granuloma; due to faulty trimming of the toenails or pressure from a tight shoe. Synonym: ingrowing toenail, onychocryptosis, onyxis, unguis aduncus, unguis incarnatus. (05 Mar 2000) |

| yellow nail | The complete or almost complete cessation of all nail growth, with thickening of the nails, increase in the convexity, loss of cuticles, and yellowing; the resulting onycholysis can cause loss of some of the nails; the condition is often associated with pulmonary disease but differs from clubbing in that the soft tissues are not hypertrophic. Synonym: yellow nail syndrome. (05 Mar 2000) |
