Question

Which of the following statements are correct?

• A. Ducts of sub-mandibular glands are Wharton's ducts.
• B. Sub-maxillary glands are the largest salivary glands.
• C. Maximum saliva is produced by the parotid gland.
• D. VII cranial nerve stimulates the parotid gland for saliva secretion.

Answer 1

Answer: (A), (C)

• Sub-mandibular duct or Wharton's duct is one of the ducts from the submandibular salivary glands. Its wall is much thicker when compared to the parotid duct. It drains saliva from each bilateral submandibular gland and sublingual glands to the sublingual caruncle at the base of the tongue.
  
• The two parotid glands are major salivary glands. These are the largest of all salivary glands, secreting the maximum amount of saliva to facilitate mastication and swallowing.
• XI cranial nerve or glossopharyngeal stimulates the parotid gland for saliva secretion.
  
• So, the correct answer is 'Ducts of sub-mandibular glands are Wharton's ducts' and 'Maximum saliva is produced by parotid gland'.
