The fifth thoracic spinal nerves, by their connection withthe superior cervical ganglion indirectly influence the tonsils. The Innervation of the Larynx.—The innervation of thelarynx is derived from the following nerves: 1. The first cervical spinal nerve, through its connectionwith the vagus and its communication with the superior cervi-cal ganglion of the sympathetic. The vagus in turn givesoff the following branches: The superior laryngeal, which 128 SPINAL ADJUSTMENT. Fig. 19. Parts Influenced by the FirstDorsal Nerve. CRANIUM, FACE AND NECK 129 is the sensory nerve of the larynx, and which arises from theinferior ganglion of the vagus; it consists principally of fila-ments from the spinal accessory, and divides into twobranches, the internal and external laryngeal. The inferior orrecurrent laryngeal nerve, also a branch of the vagus, is themotor nerve of the larynx, and unites with the cardiac branchfrom the vagus and the sympathetic. The sympathetic laryngeal nerve is one of the internalbranches of the superior cer\ical ganglion, and communicateswith the superior laryngeal nerve and its branches. 2. The second pair of cervical spinal nerves also influencethe larynx by reason of their communication with the superiorcervical ganglion of the sympathetic, and by sending fila-ments to the terminal ganglia by which these structures areinnervated. 3.
