   Inflammation of sublingual glands, called sialadenitis, occurs more frequently in these glands than in other salivary glands due to their mucous composition and drainage pattern.

   Beneath the tongue, sublingual glands lack a primary duct and instead drain through 8 to 20 minor ducts called ducts of Rivinus directly into the floor of the mouth.

   Mucous cells dominate sublingual glands, comprising roughly 70 percent of their acinar tissue, which explains their thick, stringy saliva composition.
