Sternocleidomastoid is supplied by all of the following arteries except?
Correct Answer: Thyrocervical trunk
Description: Sternocleidomastoid muscle receives its blood supply from branches of occipital and posterior auricular arteries (upper part of muscle), the superior thyroid artery or branches of the external carotid artery (middle part of muscle) and the suprascapular artery (lower part of muscle) — Gray's - 441
Although the suprascapular artery is a branch of thyrocervical trunk, it seems to be the most appropriate answer as all other options directly supply the muscle.
