Gastrointestinal physiology intermediate
Compare the three major salivary glands by location, secretion description, and associated duct as presented in the lecture.
Answer
The parotid gland is beneath the mandibular ramus at the side of the face, below and in front of the ear; it produces serous secretion carried by Stensen duct. The submaxillary gland is beneath the jaw in the submaxillary triangle, medial to the mandible; it produces mucus and serous fluids and drains through Wharton ducts. The sublingual gland lies inferior to the tongue; it produces mucus and drains through 5–15 ducts called ducts of Rivinus.
Explanation
A strong comparison links each gland to its location, secretion, and duct. The **parotid** lies near the ear and is associated with **Stensen duct** and serous fluid. The **submaxillary** gland lies beneath the jaw and is associated with mixed mucus and serous secretion and **Wharton ducts**. The **sublingual** gland lies under the tongue and is described as mucus-secreting, with **5–15 ducts of Rivinus**. **Key takeaway:** Learn the three glands as distinct location–secretion–duct combinations.\n\n**Glossary:**\n- **Serous**: Relating to a watery glandular secretion.\n- **Ducts of Rivinus**: Multiple ducts associated with the sublingual gland in the lecture.\n- **Submaxillary**: The gland also commonly called submandibular.
