alexandr1967 [171]

The parotid duct empties into the vestibule at the level of the second upper molar. Parotid vestibular submaxillary sublingual submandibula.

  • The upper second molar tooth's crown is direct across from the opening of the parotid duct, also known as Stensen's duct, which secretes serous saliva and enters the gingiva-buccal vestibule of the mouth.
  • The parotid ducts typically exit near the maxillary second molars, and they can be felt as little bumps (papillae) on both sides of the mouth. At the sublingual caruncle, the Wharton duct, the primary excretory duct of the submandibular gland, empties into the oral cavity. The sublingual caruncle is a papilla that is situated lateral to the frenulum linguae and medial to the sublingual gland. A set of lymph nodes located in front of the ear is known as the superficial parotid lymph nodes.
