Tongue: Circumvallate papillae. Eight to twelve circumvallate papillae are located along the sulcus terminalis, separating the anterior from the posterior portion of the tongue. Each papilla is surrounded by a deep sulcus that receives ducts of the serous glands of von Ebner. The connective tissue core is covered on its lateral surfaces with.
Circumvallate Papilla
Circumvallate (Vallate) Papillae. Circumvallate papillae (also known as vallate papillae) are organized linearly, as a set of four to six large papillae anterior to each limb of the sulcus terminalis (total = 8-12 papillae). The characteristic furrow found within the papillae can be appreci-ated. These moats facilitate drainage of serous salivary

Vallate papillae: These papillae lie in a V-shaped row immediately anterior to the terminal sulcus, which divides the dorsum of the tongue into its anterior two-thirds and a posterior third.. Vallate papillae are round in shape. Their apex is coated with stratified squamous epithelium. About 50% of all taste buds are found in the circumvallate papillae.

Tongue: Filiform papillae. The dorsal and lateral surfaces of the tongue are covered by specialized mucosa forming papillae: filiform, fungiform, circumvallate, and foliate. The tapering filiform papillae seen here are the most numerous type, covering most of the anterior two thirds of the tongue. Each papilla is about two to three millimeters.

Tongue: Circumvallate papillae. Along the lateral edges of the circumvallate papillae are oval taste buds, which access the oral cavity through a taste pore. Taste buds are composed of supportive cells and neuroepithelial cells that are innervated by sensory neurons of the facial nerve (cranial nerve VII). 40x, 400x.

HISTOLOGY DIAGRAMS Special histology specific points
Lingual papillae ( SG: papilla) are small structures on the upper surface of the tongue that give it its characteristic rough texture. The four types of papillae on the human tongue have different structures and are accordingly classified as circumvallate (or vallate), fungiform, filiform, and foliate. All except the filiform papillae are.

The largest and least numerous papillae found on the tongue. Furrow - each papillae is surrounded by a moat (or sulcus) that receives saliva from minor salivary glands.
Foliate Papillae With Taste Buds Photograph by Jose Calvo / Science
These papillae (namely filiform, fungiform, foliate, and circumvallate) play different roles in perception of general and special sensory stimuli. The lingual papillae (except the filiform type) and other areas of the lingual mucosa, have taste buds scattered across their surfaces. These are specialized collections of taste cells that.

Taste buds: barrel shaped, lightly staining, intramucosal sensory receptors present in large numbers on circumvallate papillae and in lesser numbers elsewhere. Intraepithelial nonkeratinocytes: melanocytes (basal), Merkel cells (basal), Langerhans cells (suprabasal) and lymphocytes occur in oral mucosa. Tonsillectomy specimens frequently.
