Which nerve provides sensory innervation to the larynx up to the level of the vocal cords?

Explanation

The internal branch of the superior laryngeal nerve supplies sensory fibers to the mucosa of the larynx above the vocal folds, including the area up to the vocal cords. The external branch mainly provides motor innervation to the cricothyroid muscle. The recurrent laryngeal nerve supplies sensory innervation below the vocal cords and motor innervation to most intrinsic laryngeal muscles. The glossopharyngeal nerve innervates the oropharynx, and the hypoglossal nerve is primarily motor to the tongue muscles.
