Larynx Flashcards
1
Q
What is the nerve supply to the larynx? Give as much detail as you can.
A
A branch from the Vagus nerve (CNX) ascends and is called the recurrent laryngeal nerve. As this nerve ascends further, it becomes named the inferior laryngeal nerve, which supplies all muscles of the larynx except for the cricothyroid, which is supplied by the external laryngeal nerve (also from CNX).
