What is pappilae?

Papillae are small, nipple-like projections found on various parts of the body, most commonly on the tongue, where they play a crucial role in the sense of taste. There are different types of papillae, including fungiform, foliate, and circumvallate, each serving specific functions in taste perception and texture. In addition to the tongue, papillae can also refer to similar structures in other tissues, such as the dermal papillae in the skin, which help anchor the epidermis and enhance nutrient exchange.
