What is the name of the duct located under the tongue?

  1. Stenson's duct

  2. Wharton's duct

  3. Bartholin's duct

  4. Sublingual duct

The correct answer is: Wharton's duct

The duct located under the tongue is known as Wharton's duct. This duct is specifically associated with the submandibular gland, which is one of the major salivary glands. Wharton's duct facilitates the drainage of saliva produced by the submandibular gland into the oral cavity, specifically at the frenulum of the tongue. Understanding the anatomy and function of Wharton's duct is essential for recognizing its clinical significance, such as in the context of salivary gland disorders or obstructions which can lead to complications like sialadenitis or the formation of salivary stones. In contrast, Stenson's duct pertains to the parotid gland, Bartholin's duct is associated with the vulvovaginal area, and the sublingual duct is linked with the sublingual gland, each serving distinct anatomical functions.
