The submandibular duct or Wharton duct[1] or submaxillary duct is one of the salivary excretory ducts. It is about 5 cm. long, and its wall is much thinner than that of the parotid duct. It drains saliva from each bilateral submandibular gland and sublingual gland to the sublingual caruncle at the base of the tongue.[2]
Structure
It begins by numerous branches from the deep surface of the gland, and runs forward between the mylohyoideus, hyoglossus, and [genioglossus] then between the sublingual gland and the genioglossus and opens by a narrow orifice on the summit of a small papilla at the side of the frenulum linguæ.
It lies superior to lingual and hypoglossal nerves.
Function
Lua error in package.lua at line 80: module 'strict' not found. This is the duct from which a hungry person, preparing to take a first bite of food, might accidentally eject a spray of salivary fluid, or, alternatively, intentionally do so in a process called gleeking.
History
It was initially described by the English anatomist Thomas Wharton and is sometimes referred to by his name.[3]
