Structurally, the sublingual gland (lat: glandula sublingualis) is a collection of glands that have their own separate excretory duct terminating in the oral cavity. It is situated below the floor of the mouth.

Unlike the parotid gland, the sublingual glands possess both mucous and serous secretory cells as seen in this image.

The sublingual gland consists mostly of mucous acini capped with serous demilunes and is therefore categorized as a mixed mucous gland with a mucous product predominating.
