The laryngeal muscles receive blood from both the subclavian and external carotid arteries. The thyrocervical trunk of the subclavian gives rise to the inferior thyroid, which gives rise to the inferior laryngeal artery. This artery enters the larynx from below. Entering the larynx from above is the superior laryngeal artery, which is a branch of the superior thyroid artery from the external carotid.
