The sympathetic innervation of the canine larynx was investigated using tyrosine hydroxylase (TH) immunohistochemistry. Many tyrosine hydroxylase immunoreactive (TH-IR) nerve fibers were observed around arteries and arterioles in the laryngeal mucosa and intrinsic laryngeal muscles. In the glandular region, TH-IR fibers were also found, with some of these fibers terminating around the basement membranes of the glandular cells. The quantity of TH-IR fibers in the mucosa differed among regions of the larynx. Many of these fibers could be found in the laryngeal surface of the epiglottis as well as the posterior glottis. These findings suggest that TH-IR fibers may directly innervate muscles in the intrinsic larynx.

D007823	Laryngeal Nerves	Branches of the VAGUS NERVE. The superior laryngeal nerves originate near the nodose ganglion and separate into external branches, which supply motor fibers to the cricothyroid muscles, and internal branches, which carry sensory fibers. The RECURRENT LARYNGEAL NERVE originates more caudally and carries efferents to all muscles of the larynx except the cricothyroid. The laryngeal nerves and their various branches also carry sensory and autonomic fibers to the laryngeal, pharyngeal, tracheal, and cardiac regions.
