| papilla pili | A knoblike indentation of the bottom of the hair follicle, upon which the hair bulb fits like a cap; it is derived from the corium and contains vascular loops for the nourishment of the hair root. Synonym: hair papilla. (05 Mar 2000) |
| papilla renalis | <anatomy> The apex of a renal pyramid that projects into a minor calyx; some 10 to 25 openings of papillary ducts occur on its tip, forming the area cribrosa. Synonym: papilla renalis. (07 Mar 2000) |
| papilla vallata | One of eight or ten projections from the dorsum of the tongue forming a row anterior to and parallel with the sulcus terminalis; each papilla is surrounded by a circular trench (fossa) having a slightly raised outer wall (vallum); on the sides of the vallate papilla and the opposed margin of the vallum are numerous taste buds. Synonym: papilla vallata, circumvallate papilla. Vascular papillae, dermal papillae containing vascular loops. (05 Mar 2000) |
| parotid papilla | The projection at the opening of the parotid duct into the vestibule of the mouth opposite the neck of the upper second molar tooth. Synonym: papilla parotidea. (05 Mar 2000) |
| renal papilla | <anatomy> The apex of a renal pyramid that projects into a minor calyx; some 10 to 25 openings of papillary ducts occur on its tip, forming the area cribrosa. Synonym: papilla renalis. (07 Mar 2000) |
| retrocuspid papilla | A small tissue tag located on the mandibular gingiva lingual to the cuspid teeth; usually occurs bilaterally, is more commonly identified in children, and is considered a normal anatomic structure. Tactile papilla, one of the papillae of the dermis containing a tactile cell or corpuscle. (05 Mar 2000) |
| circumvallate papilla | One of eight or ten projections from the dorsum of the tongue forming a row anterior to and parallel with the sulcus terminalis; each papilla is surrounded by a circular trench (fossa) having a slightly raised outer wall (vallum); on the sides of the vallate papilla and the opposed margin of the vallum are numerous taste buds. Synonym: papilla vallata, circumvallate papilla. Vascular papillae, dermal papillae containing vascular loops. (05 Mar 2000) |
| cribriform area of the renal papilla | The apex of a renal papilla pierced by 10 to 22 openings of the papillary ducts, the foramina papillaria. Synonym: area cribrosa papillae renalis. (05 Mar 2000) |
| hair papilla | Synonym: papilla pili. (05 Mar 2000) |
| dental papilla | Mesodermal tissue enclosed in the invaginated portion of the epithelial enamel organ and giving rise to the dentin and pulp. (12 Dec 1998) |
| dentinal papilla | Mesodermal tissue enclosed in the invaginated portion of the epithelial enamel organ and giving rise to the dentin and pulp. (12 Dec 1998) |
| incisive papilla | A slight elevation of the mucosa at the anterior extremity of the raphe of the palate. Synonym: papilla incisiva, palatine papilla. Interdental papilla, the gingiva that fills the interproximal space between two adjacent teeth. Synonym: gingival septum, interproximal papilla. (05 Mar 2000) |
| interproximal papilla | interdental papilla |
| optic papilla | The portion of the optic nerve seen in the fundus with the ophthalmoscope. It is formed by the meeting of all the retinal ganglion cell axons as they enter the optic nerve. Because the retina at the optic disk has no photoreceptors there is a corresponding blind spot in the visual field. (12 Dec 1998) |
