==Sublingual Salivary Gland==
*Mixed gland- [[Serous Salivary Gland - Anatomy and Physiology|serous]] and [[Mucous Salivary Gland - Anatomy & Physiology|mucous]] secretion
*Merocrine secretion
*Smaller than [[Parotid Gland - Anatomy & Physiology|parotid]] gland
*Consists of monostomatic compact part drained by a single duct. Located over rostral [[Mandibular Gland - Anatomy & Physiology|mandibluar gland]] in dog. Duct runs with [[Mandibular Gland - Anatomy & Physiology|mandibluar gland]] duct and opens at the sublingual caruncle.
*Consists of polystomatic diffuse part drained by numerous smaller ducts. Thin strip below mucosa of the floor of [[Oral Cavity Overview - Anatomy & Physiology|oral cavity]] and duct opens beside the frenulum.

==Histology==
*Tubulo-acinar gland
*[[Mucous Salivary Gland - Anatomy & Physiology|Mucous]] cells (stain lighter)
*[[Serous Salivary Gland - Anatomy and Physiology|Serous]] demilunes (stain darker)
*Demilunes secrete into lumen by canaliculi between [[Mucous Salivary Gland - Anatomy & Physiology|mucous]] cells
==Species Differences==
'''Ruminant and Pig'''
*More [[Mucous Salivary Gland - Anatomy & Physiology|mucous]] than [[Serous Salivary Gland - Anatomy and Physiology|serous]] secretion
'''Equine'''
*Diffuse part is the only part of the sublingual salivary gland present
