papilla

[pəpil′ə] pl. papillae
Etymology: L, nipple
1 a small nipple-shaped projection, such as the conoid papillae of the tongue and the papillae of the dermis that extend from collagen fibers, the capillary blood vessels, and sometimes the nerves of the dermis.

(pl. papillae) a projection from the surface of a structure; for example, tongue papillae, which carry the taste buds.

tactile papilla

skin papilla containing a touch-modulating sensory nerve ending (e.g. Merkel disc, Meissner corpuscle)

papilla 

Any small elevation shaped like a nipple. Plural: papillae. See conjunctival follicle.
Bergmeister's papilla  A cone-shaped, sheath of glial cells (astrocytes) and connective tissue covering the hyaloid artery formed during embryonic development over the optic disc and projecting into the vitreous humour. It usually atrophies before term but in some individuals it persists and a proliferation of glial cells form a glial veil. It may obscure the full view, or usually only part, of the optic disc and may sometimes suggest a disc tumour but it is in fact benign, stable and does not interfere with vision. See hyaloid remnant.
lacrimal papilla See lacrimal papilla.
papilla lacrimalis See tubercle lacrimal.
optic papilla See optic disc.

Papillae.
papilla, incisive,
n the elevation of soft tissue covering the foramen of the incisive or nasopalatine canal.
papilla, retrocuspid,
n benign nodules of the gingival tissues that occur lingual to the mandibular canines. These nodules are distinguished at a microscopic level by stellate fibroblasts within the fibrous connective tissue. Found in young adults and children, they are considered to be a normal variation of healthy tissue and should not be biopsied.
papilla(e), interproximal,
n the cone-shaped projection of the gingiva filling the interdental spaces up to the contact areas when viewed from the labial, buccal, and lingual aspects. When viewed buccolingually or labiolingually, the crest of the interproximal papilla appears as a rounded concavity at an area below the contact point of the teeth. If recession has occurred, this concavity may become an area of pathology, and the entire papilla may require reshaping to restore health. Older term:
interdental papilla(e).
papillae, central cell of the dental,
papillae, circumvallate lingual
n the small projections located at the posterior of the tongue. These projections form a V-shaped pattern located just anterior to the sulcus terminalis of the tongue. The number of circumvallate papillae varies between three and fourteen. These papillae contain taste buds along their lateral walls.
papillae, lingual,
n the small epithelial protuberances on the dorsal surface of the tongue. There are four types: circumvallate papillae, filiform papillae, foliate papillae, and fungiform papillae.
papillae, outer cell of the dental,
papillae, parotid
n.pl tiny tissue projections located on the inner portion of the buccal mucosa near the maxillary second molar that protect the parotid duct.
