*Mixed gland- [[Serous Salivary Gland - Anatomy & Physiology|serous]] and [[Mucous Salivary Gland - Anatomy & Physiology|mucous]] secretion

The sublingual salivary gland is a mixed gland producing both [[Serous Salivary Gland - Anatomy & Physiology|serous]] and [[Mucous Salivary Gland - Anatomy & Physiology|mucous]] secretions. It is smaller than a [[Parotid Gland - Anatomy & Physiology|parotid]] gland and consists of a monostomatic compact part drained by a single duct. It is located over the rostral [[Mandibular Gland - Anatomy & Physiology|mandibluar gland]] in the dog. The duct runs with the [[Mandibular Gland - Anatomy & Physiology|mandibluar gland]] duct and opens at the sublingual caruncle.

The sublingual gland consists of a polystomatic diffuse part drained by numerous smaller ducts. There is a thin strip below the mucosa of the floor of the [[Oral Cavity Overview - Anatomy & Physiology|oral cavity]] and the duct opens beside the frenulum.

*Tubulo-acinar gland

The gland is a tubulo-acinar gland containing [[Mucous Salivary Gland - Anatomy & Physiology|mucous]] cells that stain lighter. The [[Serous Salivary Gland - Anatomy & Physiology|serous]] gland demilunes stain darker. The demilunes secrete into the lumen by canaliculi between the [[Mucous Salivary Gland - Anatomy & Physiology|mucous]] cells.
