Neurovasculature of the tongue (Latin)

Sagittal section of the lower face showing the tongue (lingua) and its neurovascular supply. We can see the n. lingualis, a branch of the n. mandibularis (CN V3), and the ganglion submandibulare, a parasympathetic ganglion associated with the chorda tympani. Chorda tympani is a branch of the facial nerve (CN VII) that carries special sensory innervation to the tongue and parasympathetic innervation to the glandula submandibularis. The n. hypoglossus (CN XII) carries motor innervation to all the intrinsic muscles of the tongue (lingua). The a. lingualis originates from the a. carotis externa and gives off 3 main branches: a. dorsalis linguae, a. profunda linguae and a.sublingualis, which supply the radix linguae, the corpus linguae and the floor of the cavitas oris and glandula sublingualis, respectively. Lastly, we can see the veins that drain the tongue (lingua) into the v. jugularis interna.
