Which duct is associated with the submandibular gland?

• A. Stenson's duct
• B. Wharton's duct
• C. Rivinus duct
• D. Bartholin's duct

Answer: (B)

Wharton's duct is the duct associated with the submandibular gland. This duct is responsible for draining the saliva produced by the submandibular gland into the oral cavity. The submandibular gland itself is one of the major salivary glands and is located beneath the jaw. Wharton's duct opens at the sublingual caruncle, which is situated at the floor of the mouth, facilitating the delivery of saliva for digestion and oral health.

In contrast, Stenson's duct pertains to the parotid gland and drains saliva into the vestibule of the mouth near the second upper molar. Rivinus ducts are multiple small ducts that drain the smaller sublingual glands, while Bartholin's duct is associated with the sublingual gland, specifically draining its saliva. Thus, the specific association of Wharton's duct with the submandibular gland is crucial for understanding the anatomy and function of salivary glands.
