What are the different types of salivary glands?

Salivary Glands 1 Submandibular glands (Submaxillary glands). 2 Sublingual Glands. 3 Parotid gland. 4 Minor Salivary Glands. 5 Clinical Significance.

Where are the sublingual glands located in the mouth?

Every sublingual gland is located outright against the medial side of the mandible where it creates a shallow groove ( sublingual fossa) above the anterior one-third of the mylohyoid line. Each is outright sideways to the submandibular duct and associated lingual nerve in the floor of the oral cavity and is almond formed.
