parotid main excretory duct

The main excretory tubular canal that connects the parotid gland and the buccal mucosa and secretes a serous saliva into the vestibule of the oral cavity; it arises from the anterior surface of the gland, traversing the masseter muscle; the duct then pierces the buccinator muscle, moving medially, and opens out into the oral cavity near the second upper molar; saliva produced by acinar secretory cells in the glandular body flows sequentially through the intercalated ducts, striated ducts, and excretory ducts. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the parotid main excretory duct is

The main excretory tubular canal that connects the parotid gland and the buccal mucosa and secretes a serous saliva into the vestibule of the oral cavity; it arises from the anterior surface of the gland, traversing the masseter muscle; the duct then pierces the buccinator muscle, moving medially, and opens out into the oral cavity near the second upper molar; saliva produced by acinar secretory cells in the glandular body flows sequentially through the intercalated ducts, striated ducts, and excretory ducts. The atlas records it as a organ at the organ scale in the human body.

Where the parotid main excretory duct is

It sits in the head, within the digestive system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What the parotid main excretory duct connects to

The atlas records 3 typed relationships for it, across 3 kinds of connection. part of parotid gland.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the parotid main excretory duct. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.

Also called

Questions

Where is the parotid main excretory duct?

It sits in the head, within the digestive system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What does the parotid main excretory duct connect to?

Part of: parotid gland.

Is the parotid main excretory duct the same in other species?

Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
