DRAINAGE
Submandibular duct drains the submandibular gland and the sublingual gland. The saliva from these salivary gland goes to the sublingual caruncle present at the base of the tongue.
ANATOMICAL FEATURES
The duct passes through many structures during its course. It originates as many small branches from the salivary glands and then runs through many muscles (mylohyoideus, hyoglossus and genioglossus). It then passes between genioglossus (muscle) and sublingual gland to open at the sides of the tongue frenulum through a narrow orifice.
It also has a close relation to the lingual and hypoglossal nerves.
CLINICAL IMPORTANCE
The duct may be used, intentionally, to eject a spray of salivary fluid (this process is called gleeking). A person who hasn’t had food for some time might also do the same by accident at the first bite of food.
