A sharp-pointed depression in the enamel surface of a tooth, due to faulty or incomplete calcification or formed at the confluent point of two or more lobes of enamel. 4. To indent, as by pressure of the finger on the edematous skin; to become indented, said of the edematous tissues when pressure is applied with the fingertip. [L. puteus]- anal p. SYN: proctodeum (1).- buccal p. a structural depression found on the buccal enamel of molars.- coated p. specialized depressions on the cell surface involved in receptor-mediated endocytosis; the visible proteinaceous layer on the cytosolic side of the depression provides the coated appearance.- commisural pits similar to lip pits but found at the labial commisures.- costal p. of transverse process SYN: transverse costal facet.- gastric p. [TA] one of the numerous small pits in the mucous membrane of the stomach that are the mouths of the gastric glands. SYN: foveola gastrica [TA].- iris pits colobomas affecting the stroma of the iris with pigment epithelium intact.- lens pits the paired depressions formed in the superficial ectoderm of the embryonic head as the lens placodes sink in toward the optic cup; the external openings of the pits are closed as the lens vesicles are formed.- lip pits malformations of the lip seen in unilateral or bilateral depressions or fistulae. May be hereditary or associated with cleft lip and/or palate.- nail pits small punctate depressions on the surface of the nail plate due to defective nail formation; seen in psoriasis and other disorders. SEE ALSO: geographic stippling of nails.- nasal pits the paired depressions formed when the nasal placodes come to lie below the general external contour of the developing face as a result of the rapid growth of the adjacent nasal elevations; the pits are the primordia of the rostral portions of the nasal chambers. SYN: olfactory pits.- optic p. a congenital anomaly characterized by a focal depression of the temporal optic nerve head.- otic pits paired depression, one on either side of the head of the embryo, marking the location of the future auditory vesicles. SYN: auditory pits.- preauricular p.
