What is the duct associated with the submandibular gland located under the tongue?

The duct associated with the submandibular gland that is located under the tongue is Wharton's duct. This duct transports saliva from the submandibular gland, which is one of the major salivary glands, to the oral cavity. Wharton's duct opens at the sublingual caruncle, which is the small elevation found on either side of the lingual frenulum under the tongue.

Understanding the anatomical positioning and function of Wharton's duct is essential for recognizing how saliva is delivered to the mouth, which plays a vital role in digestion and oral health. Other ducts mentioned, such as Stenson's duct, are associated with different salivary glands (in this case, the parotid gland), while Sjogren's syndrome pertains to an autoimmune condition affecting salivary glands rather than a specific duct, and Bartholin's duct relates to the female reproductive system, specifically the Bartholin gland. This highlights Wharton's duct as the correct and relevant answer in the context of the submandibular gland.
