a soft, fleshy projection, usually small and nipple-like.
One of the small bumps on the upper surface of the tongue. (papilla, singular; papillae, plural)
n. (L. papilla, nipple) a glandular hair with one secreting cell above the epidermis level.
(-ae) L. = a teat, a nipple; a nipple-like projection, e.g., on the tonge (Malpighi, c. 1670; cf. circumvallate, filiform, foliate, fungiform, vallate); duodenal papilla (containing duodenal ampulla); optic papilla; renal papilla (Berengarius, c. 1480-1550).
a small fleshy projection
a small projection of tissue at the base of a hair or tooth or feather
A vascular mass of connective tissue beginning in the dermis and extending (upward into epidermis) into and nourishing the hair root.
The papilla is found at the base of the hair follicle. This is the primary location where the cells that form hair are produced. Blood vessels are connected to the papilla, which send necessary proteins and vitamins to the roots to nourish the hair.
is the very root of the hair, where living hair cells are produced.
(paw-PIHL-aw) A small finger-shaped projection.
(pl. papillae) A projection from the surface of a structure, such as tongue papillae, which carry the taste buds.
a small soft superficial gland or protuberance.
Latin = nipple or teat; adjective - papillary.
(pl. papillae, adj. papillate) ( Wodehouse, 1935) A small protuberance. Comment: The term is mostly used in describing pollen of Taxodiaceae (Gymnospermae). Papilla (pl. papillae, adj. papillate) ( Traverse, 1955) A general term, applied in palynology to parallel sided exinous elements with rounded apices, less than 1µm in length. See also: scabrate. * Paracavate (adj.) ( Balme, 1988) An exine in which the intexine is clearly defined but in which its degree of separation from the exoexine is uncertain or indeterminate. Example: Ancyrospora langii.* Paraisopolar ( Praglowski et al., 1983) Describing a pollen grain whose polar faces differ only in the attachment of viscin threads to the proximal pole. Synonym of subisopolar. Comment: Most pollen grains with viscin threads have polar faces of which one is less/more convex than the other.
vascular process of connective tissue extending into and nourishing the roots of the hair.
(on spores) small nipple-like protuberance.
A small nipple-like projection, such as a protuberance or bulge on the skin. adj.: papillary
A nipple-like projection or structure.
a small, elongated protuberance on the surface of an organ, usually an extension of one epidermal cell. adj. papillose.
A small round or conical projection on the skin, at the root of a hair or feather, or at the base of a developing tooth. 2. One of the small, rounded projections of the upper tongue surface of vertebrates that contain taste buds.
A minute nipple-shaped projection.
The small root area at the base of hair, which receives the nutrients from the follicle needed for hair growth.
any type of nipple shaped object, such as the nipple of the breast.
any cone-shaped protuberance projecting from the surface of an organ or organism. Papillae occur, for example, on the tongue, in the kidneys, in plants, on the surface of many petals and leaves, and in algae, on the surface of the blades.
a small nipple like protuberance (eg papillary ridge: the ridges of the finger from which fingerprints come).
Connective tissue from which hair is generated from the follicle.
A short nipple-like outgrowth.
Any small, soft rounded protuberance on the skin.
A small nipple-shaped elevation.
The small area at the base of the hair root which provides nutrients needed for growth.
A small nipple-shaped projection.
