Final answer:
Fungiform papillae are the types of lingual papillae that contain about three taste buds per papilla, and they are found over a large area of the tongue.
Step-by-step explanation:
The type of lingual papillae that contain about three taste buds per papilla are the fungiform papillae. These mushroom-shaped structures cover a large area of the tongue, with larger ones found toward the rear and smaller ones on the tip and sides. Unlike the filiform papillae, which have touch receptors and create an abrasive surface, the fungiform papillae contain taste buds and are primarily involved in gustation. The other types of papillae mentioned, such as foliate and circumvallate, contain a much higher number of taste buds, with foliate papillae housing about 1,300 taste buds within their folds and each circumvallate papilla containing about 250 taste buds.
Foliate papillae are the type of lingual papillae that contain about three taste buds per papillae. They are leaf-like papillae located in parallel folds along the edges and toward the back of the tongue. Foliate papillae contain about 1,300 taste buds within their folds.
Other types of lingual papillae include circumvallate papillae, which are wall-like papillae at the back of the tongue containing about 250 taste buds, and fungiform papillae, which are mushroom-shaped papillae containing taste buds as well.
