Vol. 11--19 In common with the other ganglia developed in connection with the branches of the trigeminal nerve, this ganglion has three roots--viz. (i) a sensory root from the lingual nerve; (2), a secretory root from the chorda tympani; and (3) a sympathetic root from the plexus around the external maxillary artery. From its lower border several minute twigs proceed, and these are distributed--(i) to the submaxillary gland and duct; (2) to the sublingual gland from the branch which it gives to the lingual nerve; and (3) to the mucous membrane of the mouth. Nervus Hypoglossus.--This nerve has been traced in the dissection of the anterior triangle to the point where it disappears under cover of the mylo-hyoid muscle (p. 231). It is now seen passing anteriorly upon the hyoglossus muscle, above the hyoid bone and below the level of the deep part of the submaxillary gland. At the anterior border of the hyoglossus it gains the surface of the genio-glossus muscle, into the substance of which it sinks; and finally it breaks up into branches which supply the muscular substance of the tongue. Upon the hyoglossus muscle it is accompanied by a vena comitans. The branches which spring from the hypoglossal nerve in this region are very numerous, and are entirely distributed to muscles.
