D
At the posterior wall of the oropharynx
Verified step by step guidance
1
Understand the anatomy of the submandibular salivary glands: These are paired glands located beneath the lower jaw (mandible) and are responsible for producing saliva to aid in digestion and oral health.
Learn about the ducts associated with the submandibular glands: The submandibular ducts, also known as Wharton's ducts, are the pathways through which saliva is transported from the glands to the oral cavity.
Identify the location where Wharton's ducts open: The ducts empty into the oral cavity at the base of the lingual frenulum, which is the fold of tissue connecting the underside of the tongue to the floor of the mouth.
Eliminate incorrect options: The hard palate, near the upper second molar, and the posterior wall of the oropharynx are not associated with the submandibular ducts. These locations are related to other anatomical structures or glands.
Confirm the correct answer: The ducts of the submandibular salivary glands empty into the oral cavity at the base of the lingual frenulum, ensuring saliva is delivered near the tongue for effective mixing with food during chewing.
