sublingual duct

"Walther's ducts": Also known as minor sublingual ducts.

The largest of all, the sublingual duct (of Bartholin) joins the submandibular duct to drain through the sublingual caruncle.

One or more join to form the major sublingual duct (larger sublingual duct, duct of Bartholin), which opens into the submandibular duct.

The ducts are then crossed by the lingual nerve, and ultimately drain into the sublingual caruncles (caruncula sublingualis) on either side of the lingual frenulum along with the major sublingual duct (Bartholin).

Most of the remaining small sublingual ducts open separately into the mouth on an elevated crest of mucous membrane, the plica fimbriata, formed by the gland and located on either side of the frenulum linguae.
