==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.
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==
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.
