What does the Brachiocephalic artery divide into?

1. Left common carotid artery and subclavian artery

2. Right subclavian artery and common carotid artery

3. Left subclavian artery only

4. Right atrial artery and right common carotid artery

The correct answer is: Right subclavian artery and common carotid artery

The Brachiocephalic artery, also known as the innominate artery, is a major vessel arising from the aorta that plays a key role in supplying blood to the right side of the head and neck as well as the right upper limb. It divides into two primary branches: the right common carotid artery, which supplies blood to the right side of the head and neck, and the right subclavian artery, which supplies blood to the right arm. This branching is significant in understanding the vascular anatomy of the upper body, as these arteries provide essential blood flow to major regions. The right common carotid artery, after its origin from the Brachiocephalic artery, ascends in the neck to bifurcate into the external and internal carotid arteries. Meanwhile, the right subclavian artery continues to provide circulation to the right arm and shoulder area. The other options listed don't reflect the accurate branching of the Brachiocephalic artery. The left common carotid and left subclavian arteries arise directly from the aortic arch, while the suggestion of a right atrial artery is incorrect as there is no such artery in the context of this branching pattern in the circulatory system.
