Which nerve provides innervation to the cricothyroid muscle?

Explanation

The cricothyroid muscle receives its nerve supply from the external branch of the superior laryngeal nerve. The recurrent laryngeal nerve innervates most other intrinsic muscles of the larynx, while the internal branch provides sensory innervation to the laryngeal mucosa. The hypoglossal nerve controls tongue movements and does not supply the cricothyroid.
