duodenal papilla  either of two small elevations on the mucosa of the duodenum, the major at the entrance of the conjoined pancreatic and common bile ducts and the minor at the entrance of the accessory pancreatic duct.

filiform papillae  threadlike elevations covering most of the tongue surface.

foliate papillae  parallel mucosal folds on the tongue margin at the junction of its body and root.

fungiform papillae  knoblike projections of the tongue scattered among the filiform papillae.

gingival papilla  the cone-shaped pad of gingiva filling the space between the teeth up to the contact area.

hair papilla  the fibrovascular mesodermal papilla enclosed within the hair bulb.

incisive papilla  an elevation at the anterior end of the raphe of the palate.

interdental papilla  gingival p.

lacrimal papilla  one in the conjunctiva near the medial angle of the eye.

lingual papillae  see conical, filiform, foliate, fungiform, and vallate papillae.

mammary papilla  nipple (1).

optic papilla  optic disk.

palatine papilla  incisive p.

papilla pi´li  hair p.

renal papillae  the blunted apices of the renal pyramids.

tactile papilla  see under corpuscle.

urethral papilla  a slight elevation in the vestibule of the vagina at the external orifice of the urethra.

vallate papillae  eight to twelve large papillae arranged in a V near the base of the tongue.

buccal papilla

see under dental, conical, lingual etc. papilla (below).

circumvallate papilla

vallate papilla.

conical papilla

one of the sparsely scattered fleshy elevations on the tongue or lining the cheeks of cattle.

papilla 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 papilla, dentinal papilla

the small mass of condensed mesenchyme capped by each of the enamel organs in a developing tooth.

dermal papilla

finger- and ridge-like projections of the dermis which interdigitate with similar depressions in the epidermis.

duodenal papilla

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 papilla

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 papilla

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 papilla

one of the knob-like projections of the tongue scattered among the filiform papillae.

gingival papilla

the triangular pad of the gingiva filling the space between the proximal surfaces of two adjacent teeth.

hair papilla

the fibrovascular mesodermal papilla enclosed within the hair bulb.

ileal papilla

papilla carrying the terminal orifice of the ileum and its entrance to the large bowel.

incisive papilla

an elevation at the anterior end of the raphe of the palate onto which the incisive ducts open.

lacrimal papilla

see lacrimal punctum.

lingual papilla

elevations on the surface of the tongue, containing the taste buds; the conical, filiform, foliate, fungiform and vallate papillae.

major duodenal papilla

the papilla in the duodenum for the common opening of the bile duct and the pancreatic duct.

mammary papilla

the teat or nipple of the mammary gland.

marginal tongue papilla

temporary filiform papillae in puppies, piglets and kittens which are thought to facilitate sucking.

optic papilla

optic disk.

palatine papilla

incisive papilla.

parotid papilla

the oral opening of the duct of the parotid salivary gland located opposite the third upper molar.

papilla pili

hair papilla.

renal papilla

the blunted apex of a renal pyramid.

ruminal papilla

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 papilla

tactile corpuscles.

terminal hoof papilla

papillae on the distal ends of the sensitive laminae of the hoof.

tongue papilla

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.

papilla unguiculiformes

horny claw-shaped papillae at the reticulo-omasal orifice.

urethral papilla

a slight elevation in the vestibule of the vagina at the external orifice of the urethra.

vallate papilla

one of the eight to 12 large circular papillae arranged in a V near the base of the tongue.

papilla of Vater, Vater's papilla

major duodenal papilla.
