The paired sublingual glands are major salivary glands in the mouth. It is the smallest, most diffuse, and the only unencapsulated major salivary gland. It provides only 3-5% of the total salivary volume.[1]

Structure
They lie anterior to the submandibular gland inferior to the tongue, as well as beneath the mucous membrane of the floor of the mouth. Each gland is effectively palpated on the floor of the mouth posterior to each mandibular canine. Placing one index finger intraorally and the fingertips of the opposite hand extraorally, the compressed gland is manually palpated between the inner and outer fingers.[2]
They are drained by 8-20 excretory ducts called the ducts of Rivinus.[3] The largest of all, the sublingual duct (of Bartholin) joins the submandibular duct to drain through the sublingual caruncle. The sublingual caruncle is a small papilla near the midline of the floor of the mouth on each side of the lingual frenum.[2] Most of the remaining small sublingual ducts open separately into the mouth on an elevated crest of mucous membrane, the plica fimbriata, formed by the gland and located on either side of the frenulum linguae.
Histology
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. Presence of striated ducts and intercalated ducts.[1]
Innervation and blood supply
The chorda tympani nerve (from the facial nerve via the submandibular ganglion) is secretomotor and provides parasympathetic supply to the sublingual glands. The gland receives its blood supply from the sublingual and submental arteries.[3] Lymph from the sublingual salivary gland drains into the submandibular lymph nodes.[2]
Development
The sublingual salivary glands appear in the eighth week of prenatal development, two weeks later than the other two major salivary glands. They develop from epithelial buds in the sulcus surrounding the sublingual folds on the floor of the mouth, lateral to the developing submandibular gland. These buds branch and form into cords that canalize to form the sublingual ducts associated with the gland. The rounded terminal ends of the cords form acini.[1]
Clinical significance
See also: Salivary gland disease
Ranulas are the most common pathologic lesion associated with the sublingual glands.[4]
