The '''mandibular gland''' produces a '''merocrine''' secretion. 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.

*Compact

+

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'''.

==Innervation==

+

The mandibular gland is innervated by the '''facial''' nerve ([[Cranial Nerves - Anatomy & Physiology|CN VII]]) via the '''chordi tympanii''' of the '''trigeminal''' nerve ([[Cranial Nerves - Anatomy & Physiology|CN V]]).

*Mainly [[Mucous Salivary Gland - Anatomy & Physiology|mucous]] ~~secretion~~ in dog and cat

+

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.
