| + | 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'''. |

| + | 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. |

− | *Compact
| + | ==Innervation== |
| | | |
− | *Located around angle of jaw
| + | 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]]). |
