Sternocleidomastoid is supplied by all of the following aeries except?
**Core Concept**
The sternocleidomastoid muscle is a key structure in the cervical region, involved in movements of the neck and head. Its blood supply is crucial for its function and maintenance.
**Why the Correct Answer is Right**
The sternocleidomastoid muscle is primarily supplied by branches from the occipital artery, deep cervical artery, and the inferior thyroid arteries. These arteries provide the necessary blood flow for the muscle's growth, repair, and function. The occipital artery typically gives off the transverse sternocleidomastoid branch, while the deep cervical artery and inferior thyroid arteries contribute to the muscle's blood supply through their terminal branches.
