The sensation above the vocal cords is carried by the internal branch of the superior laryngeal nerve, a sensory branch of the vagus. This branch enters the larynx through the thyrohyoid membrane and supplies the mucosa of the supraglottic region, including the epiglottis and the aryepiglottic folds. The external branch of the superior laryngeal nerve, by contrast, is motor to the cricothyroid muscle and does not convey sensation. The glossopharyngeal nerve mainly handles sensation from the oropharynx and posterior tongue, not the laryngeal mucosa above the cords. While the vagus nerve gives many branches, the specific sensory input above the cords comes from this internal branch of the superior laryngeal nerve.
