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

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

see lacrimal punctum.
lingual papilla
elevations on the surface of the tongue, containing the taste buds; the conical, filiform, foliate, fungiform and vallate papillae.

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

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.

This study was undertaken to measure the effect of EGCG on hair growth in vitro and to investigate its effect on human dermal papilla cells (DPCs) in vivo and in vitro.

Dermal papilla cells (DPCs), a group of specialized fibroblasts within the hair follicle bulb, have an essential function in the control of hair growth not only in the normal hair cycle but also in the pathogenesis of certain conditions, for example in androgenetic alopecia (Inui et al.
I go into each follicle with a very fine gold needle and pass an electric current along that needle to destroy a dermal papilla, which means hair never grows again.
