Pl. papillae [L.] a small, nipple-shaped projection or elevation.

• buccal p. — see under dental, conical, lingual etc. papilla (below).
• circumvallate p. — vallate papilla.
• conical p. — one of the sparsely scattered fleshy elevations on the tongue or lining the cheeks of cattle.
• p. of corium — conical extensions of the fibers, capillary blood vessels, and sometimes nerves of the corium into corresponding spaces among downward- or inward-projecting rete ridges on the undersurface of the epidermis. Special papillae coriales occur on the sensitive corium of the frog of the horse's hoof.
• dental p., dentinal p. — the small mass of condensed mesenchyme capped by each of the enamel organs in a developing tooth.
• dermal p. — finger- and ridge-like projections of the dermis which interdigitate with similar depressions in the epidermis.
• duodenal p. — either of the small elevations (major and minor) on the mucosa of the duodenum, the major at the entrance of the conjoined pancreatic and common bile ducts, the minor at the entrance of the accessory pancreatic duct.
• filiform p. — one of the short threadlike elevations covering most of the tongue surface. In cats and cattle they are heavily cornified to give a rasping tongue.
• foliate p. — one of the parallel mucosal folds on the tongue margin at the junction of its body and root, best developed in the horse and pig but rudimentary or absent from other domestic animals.
• fungiform p. — one of the knob-like projections of the tongue scattered among the filiform papillae.
• gingival p. — the triangular pad of the gingiva filling the space between the proximal surfaces of two adjacent teeth.
• hair p. — the fibrovascular mesodermal papilla enclosed within the hair bulb.
• ileal p. — papilla carrying the terminal orifice of the ileum and its entrance to the large bowel.
• incisive p. — an elevation at the anterior end of the raphe of the palate onto which the incisive ducts open.
• lacrimal p. — see lacrimal punctum.
• lingual p. — elevations on the surface of the tongue, containing the taste buds; the conical, filiform, foliate, fungiform and vallate papillae.
• major duodenal p. — the papilla in the duodenum for the common opening of the bile duct and the pancreatic duct.
• mammary p. — the teat or nipple of the mammary gland.
• marginal tongue p. — temporary filiform papillae in puppies, piglets and kittens which are thought to facilitate sucking.
• optic p. — optic disk.
• palatine p. — incisive papilla.
• parotid p. — the oral opening of the duct of the parotid salivary gland located opposite the third upper molar.
• p. pili — hair papilla.
• renal p. — the blunted apex of a renal pyramid.
• ruminal p. — papillae up to 0.5 inch long, flat or filiform that cover most of the ruminal wall but are absent from the pillars and the dorsal part of the dorsal sac.
• tactile p. — tactile corpuscles.
• terminal hoof p. — papillae on the distal ends of the sensitive laminae of the hoof.
• tongue p. — small projections from the mucous membrane of the tongue that include filiform, lenticular, fungiform, foliate and vallate papillae; most are to assist in grooming, food prehension and movement; some carry orifices for glands and others for taste.
• p. unguiculiformes — horny claw-shaped papillae at the reticulo-omasal orifice.
• urethral p. — a slight elevation in the vestibule of the vagina at the external orifice of the urethra.
• vallate p. — one of the eight to 12 large circular papillae arranged in a V near the base of the tongue.
• p. of Vater, Vater's p. — major duodenal papilla.
• wool p. — as for hair papilla (above).
