Submandibular ganglion

Other Terms: Ganglion submandibulare, Ganglion submandibulaire


The submandibular ganglion is the smallest of the sympathetic ganglia connected with the trigeminal nerve. It is situated upon the hyoglossus muscle, between the lingual nerve and the deep portion of the submandibular gland beneath the posterior border of the mylohyoid muscle. It is suspended from the lingual nerve by two small filaments. Like the other ganglia of the head, it is connected with the branches of the trigeminal nerve. It receives filaments of communication of three kinds: motor, sensory, and sympathetic. Its motor root arises from the facial nerve through the chorda tympani. The sensory branches are derived from the lingual nerve. Its connection with the cervical sympathetic is through a branch which comes from the sympathetic plexus around the facial artery. Its five or six branches of distribution supply the mucous membrane of the floor of the mouth and the submandibular gland and its duct.
