Major sublingual duct
The excretory ducts of the sublingual gland are from eight to twenty in number. Of the smaller sublingual ducts, some join the submandibular duct; others open separately into the mouth, on the elevated crest of mucous membrane, caused by the projection of the gland, on either side of the frenulum linguae. One or more join to form the major sublingual duct, which opens into the submandibular duct.
