Final answer:
The sublingual salivary glands contribute to only a small amount of the total saliva produced, approximately 3-5%.
Step-by-step explanation:
The sublingual salivary glands are a pair of major salivary glands located below the tongue. These glands secrete saliva into the oral cavity through multiple tiny sublingual ducts that open onto the inferior surface of the oral cavity, posterior to the submandibular papilla. However, the sublingual glands contribute to only a small amount of the total saliva production, accounting for approximately 3-5% of the total saliva.
