抄録

As a part of the work to accomplish the precise topography of the intaralingual nerves, the peripheral distribution of the hypoglossal and lingual nerves in the human tongue was studied with special attention to the communication between those. The average courses of each nerve were summarized as follows: 1) The main trunk of the hypoglossal nerve (HN) rounds the anterior border of the hyoglossus muscle (HGM), bends medially with an acute angle, and enters the muscular fibers of the genioglossus muscle (GGM) . Near the median plane, the HN changes direction anterosuperiorly, and runs for the dorsum of the tongue. On reaching the layer of the longitunalis superior muscle, the HN comes close to the deep lingual artery. The HN ramifies, radiates parallel to the dorsum of the tongue, and terminates within the intrinsic muscular fibers at the lateral border and apex of the tongue. 2) The lingual nerve (LN) forms a plexiform extralingual connection with the HN near the anterior border of the HGM. There the LN furcatets a branch to the mucosa of the central margin of the tongue. Turning the anterosuperior border of the HGM medially, the LN gives off a branch that is distributed to the medial mucosa of the body of the tongue. The main trunk of the LN passes anterosupenorly through the space between the longitudinalis inferior muscle and the GGM, branches off the sensory twigs to the anterior third of the tongue, and reach the apex. 3) The communications between the HN and LN are formed at the extralingual site lateral to the HGM, at the intralingual site around the GGM, and near the apex of the tongue.
