These are structures of specialized mucosa involved with taste

115
Q

Filiform lingual papillae

A

The slender, threadlike papillae. Give the dorsal surface its velvety texture

116
Q

Fungiform lingual papillae

A

Red mushroom shaped dots, larger in size then the filiform papillae

117
Q

Foliate lingual papillae

A

Side or lateral surface of the tongue, known for its vertical ridges. These contain taste buds

A

These faces are formed laterally on each side of the folds of tissue (also called the tonsillar pillars or palatal arches)

132
Q

Palatine tonsils

A

Located between each of the anterior and posterior faucial pillars or folds of tissue created by underlying muscles
