Saliva drainage involves a system where saliva produced by salivary glands is transported to the oral cavity and the venous drainage from the glands. The information available focuses on the drainage of the parotid gland.
Parotid Gland Saliva Drainage
The parotid gland, one of the major salivary glands, releases saliva into the mouth through a specific duct. The venous drainage from the parotid gland is facilitated via the external jugular vein.
Stensen's Duct
- The duct of the parotid gland, also known as the Stensen duct, plays a vital role.
- This duct runs across the masseter muscle.
- It then empties into the oral cavity at the level of the upper second molar.
Venous Drainage
- The parotid gland's venous drainage is provided by the external jugular vein.
In summary, saliva, once secreted from the parotid gland, drains into the oral cavity via the Stensen's duct. Venous blood from the parotid gland drains into the external jugular vein.
