==Overview==
[[File:Salivary glands.jpg|500px|right|thumb|Dog salivary glands]]
The '''mandibular gland''' produces a '''merocrine''' secretion, which means it is a mixed gland - [[Serous Salivary Gland - Anatomy & Physiology|serous]] and [[Mucous Salivary Gland - Anatomy & Physiology|mucous]] secretions.
It is generally smaller than the '''[[Parotid Gland - Anatomy & Physiology|parotid]]''' gland and is a moderately large gland in carnivores and herbivores. It is compact and located around the angle of the jaw.

==Mandibular Salivary Gland==

The '''mandibular duct''' runs ventral to the mucous membrane of the floor of the [[Oral Cavity Overview - Anatomy & Physiology|oral cavity]], close to the '''frenulum''' of the [[Tongue - Anatomy & Physiology|tongue]]. The duct opens at the '''sublingual caruncle'''.
==Histology==
==Histology==
The mandibular gland is known as a '''tubulo-acinar gland'''. It consists of [[Mucous Salivary Gland - Anatomy & Physiology|mucous]] cells that stain lighter and [[Serous Salivary Gland - Anatomy & Physiology|serous]] demilunes that stain darker. '''Demilunes''' secrete into lumen by canaliculi between mucous cells.
==Innervation==
The mandibular gland is innervated by the '''facial''' nerve ([[Cranial Nerves - Anatomy & Physiology|CN VII]]) via the '''chordi tympanii''' and by the '''trigeminal''' nerve ([[Cranial Nerves - Anatomy & Physiology|CN V]]).
==Species Differences==
==Species Differences==
===Carnivores===
The mandibular gland produces mainly [[Mucous Salivary Gland - Anatomy & Physiology|mucous]] secretions in the dog and cat. It is an oval shape in the canid.
===Herbivores===
The mandibular gland in herbivores is larger and deeper.
