Mandibular Salivary Gland - Copyright Nottingham 2008

Overview

The mandibular gland produces a merocrine secretion. It is generally smaller than the 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, close to the frenulum of the tongue. The duct opens at the sublingual caruncle.

Innervation

The mandibular gland is innervated by the facial nerve (CN VII) via the chordi tympanii of the trigeminal nerve (CN V).

Species Differences

Carnivores

The mandibular gland produces mainly 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.
