Now identify the thyrohyoid membrane extending between the thyroid cartilage and the hyoid bone. Identify the internal laryngeal nerve, a branch of the superior laryngeal nerve, as it pierces the membrane to supply sensory innervation to the superior portion of the larynx. Identify the superior laryngeal artery, a branch of the superior thyroid artery, and the superior laryngeal vein which also accompany the internal laryngeal nerve. Identify the external laryngeal nerve [tip of probe], another branch of the superior laryngeal nerve, which innervates the cricothyroid muscle.
