**The lingual branch** is a section of the large salivary gland (palatum major) on the upper jaw, located midway between the lower nasal and two upper lips. This section is called the small uvula, since it is a triangular-shaped conical protrusion of the tongue. On the anterior wall of the small uvula, two lateral (side) transverse branches (rami transversi) extend from the mucous membrane in different places, in front of which there is a large transverse branch connecting the small uvula and the floor of the mouth, respectively (at the level of the second upper molar). The branches are connected to each other in the region of the large transverse branch. The lateral (lateral) and medial (middle) lingual branches can end in one thick branch, branching in the large uvula into medium and small (pharyngeal and palatine) branches.
