Abstract
The nucleus tractus solitarius (NTS) is subdivided into nine subnuclei based on their cellular morphology. The NTS receives afferent input from the vagus, glossopharyngeal, and facial nerves. The NTS neurons mainly project to the medulla oblongata, pons, and thalamus and are involved in the regulation of respiration, heart and blood vessels, taste, and neurohypophysial hormone secretion. A variety of neurotransmitters have been identified in the somata and axons of the NTS neurons. Sensory nerve fibers in the larynx project through the internal branch of the superior laryngeal nerve to the interstitial subnucleus on the central side, and their somata are located in the nodose ganglion. We showed that sensory nerve fibers in the rat inferior laryngeal nerve project to the interstitial subnucleus, using wheat germ agglutinin-horseradish peroxidase (WGA-HRP) as a transganglionic tracer.
