Submandibular duct

The submandibular duct (also known as Wharton's duct) allows the passage of saliva from the submandibular gland to the sublingual papilla located anteriorly.

The duct extends anteriorly from the submandibular gland superior to the lingual nerve and submandibular ganglion curving over the posterior edge of the mylohyoid muscle into the sublingual space. It is approximately 5-6 cm in length and has a diameter of approximately 1-3 mm on conventional sialographic images.

It runs forward with lingual nerve and vein and hypoglossal nerve and opens into the sublingual papilla at the side of the frenulum of the tongue.
