The interdental papilla, also known as the interdental gingiva, is the part of the gums (gingiva) that exists coronal to the free gingival margin on the mesial and distal surfaces of the teeth. The interdental papillae fill in the area between the teeth apical to their contact areas to prevent food impaction; they assume a conical shape for the ...
Circumvallate papilla in vertical section, showing arrangement of the taste-buds and nerves. The circumvallate papillae (or vallate papillae) are dome-shaped structures on the human tongue that vary in number from 8 to 12. They are situated on the surface of the tongue immediately in front of the foramen cecum and sulcus terminalis, forming a ...
In embryology and prenatal development, the dental papilla is a condensation of ectomesenchymal cells called odontoblasts, seen in histologic sections of a developing tooth. It lies below a cellular aggregation known as the enamel organ. The dental papilla appears after 8–10 weeks of intra uteral life.
The dense layer is the deeper layer of the lamina propria. It consists of dense connective tissue with a large amount of fibers. Between the papillary layer and the deeper layers of the lamina propria is a capillary plexus, which provides nutrition for the all layers of the mucosa and sends capillaries into the connective tissue papillae.

Its two nerve fibers (axons) running with spiral coils around the tactile corpuscle. Apparent termination of one of these fibers.

The incisive foramen is a funnel-shaped opening in the bone of the oral hard palate representing the inferior termination of the incisive canal. [citation needed] An oral prominence - the incisive papilla - overlies the incisive fossa.
The junction between the foregut and midgut occurs directly below the major duodenal papilla. [3]: 274 The major duodenal papilla projects less than a centimetre into the lumen of the duodenum. [4] It appears rounded and is often covered by a fold on the uppermost side of the papilla; that is, the side which receives contents from the stomach. [4]
Geographic tongue is characterized by areas of atrophy and depapillation (loss of papillae), leaving an erythematous (darker red) and smoother surface than the unaffected areas. The depapillated areas are usually well-demarcated, [ 4 ] and bordered by a slightly raised, white, yellow or grey, serpiginous (snaking) peripheral zone. [ 9 ]
