==Mandibular Salivary Gland==

*Mixed gland - [[Serous Salivary Gland - Anatomy and Physiology|serous]] and [[Mucous Salivary Gland - Anatomy & Physiology|mucous]] secretion
*Merocrine secretion
*Generally smaller than the [[Parotid Gland - Anatomy & Physiology|parotid]] gland
*It is a moderately large gland in carnivores
*It is a large gland in herbivores
*Compact
*Located around angle of jaw
*Mandibular duct runs ventral to mucous membrane of floor of [[Oral Cavity Overview - Anatomy & Physiology|oral cavity]], close to frenulum of [[Oral Cavity - Tongue - Anatomy & Physiology|tongue]]
*Duct opens at sublingual caruncle
*Innervated by facial nerve ([[Nervous System - CNS - Anatomy & Physiology#Innervation - Cranial Nerves|CN VII]]) via chordi tympanii of trigeminal ([[Nervous System - CNS - Anatomy & Physiology#Innervation - Cranial Nerves|CN V]])
==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 cells
==Species Differences==
'''Carnivores'''
*Mainly [[Mucous Salivary Gland - Anatomy & Physiology|mucous]] secretion in dog and cat
*Oval shape in canid
'''Herbivores'''
*Larger and deeper
