In human anatomy, the mouth is the first portion of the alimentary canal that receives food and produces saliva. [2] The oral mucosa is the mucous membrane epithelium lining the inside of the mouth. In addition to its primary role as the beginning of the digestive system, the mouth also plays a significant role in communication.
The fimbriated fold of tongue, also plica fimbriata, is a slight fold of the mucous membrane on the underside of the tongue which runs laterally on either side of the frenulum. The free edge of the fimbriated fold occasionally exhibits a series of fringe-like processes. (Fimbria is Latin for fringe).
The underside of a human tongue, showing its rich blood supply. The tongue is a muscular hydrostat that forms part of the floor of the oral cavity. The left and right sides of the tongue are separated by a vertical section of fibrous tissue known as the lingual septum. This division is along the length of the tongue save for the very back of ...
The thin strip of tissue that runs vertically from the floor of the mouth to the undersurface of the tongue is called the lingual frenulum. It tends to limit the movement of the tongue, and in some people, it is so short that it actually interferes with speaking. A hump of tissue near the base of the tongue houses a series of saliva gland ducts.
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 row on either side; the two rows run backward and medially, and meet in the midline.
the mucosa of the floor of mouth and the tongue superiorly; the mylohyoid muscle inferiorly; the medial surface of the mandible anterolaterally; the muscles along the base of the tongue (geniohyoid and genioglossus muscles) posteriorly; medially, the intrinsic muscles of the tongue and genioglossus separate the two halves of the sublingual space.

Anatomy of the human mouth, including the frenulum of the tongue. A frenulum / ˈ f r ɛ n j ʊ l əm / or frenum / ˈ f r iː n əm / (pl.: frenula or frena, from the Latin frēnulum, "little bridle", the diminutive of frēnum [1]) is a small fold of tissue that secures the motion of a mobile organ in the body.
