Question

Are there two brachial arteries in the body? Are there two brachiocephalic arteries in the body?

Answer 1

There are two Brachial arteries but only one Brachiocephalic artery in the body.

The brachiocephalic artery is in right side and shortly after its commencement it gives rise to right common carotid artery and right subclavian artery.

Whereas in the left side, the left common carotid artery and the left subclavian artery arises directly from the arch of aorta. So, there is no left brachiocephalic artery. And we are left with only one brachiocephalic artery.

The right and left subclavian arteries then supply right and left arm by forming right and left axillary arteries. The axillary artery in each arm then gives rise to brachial artery. Yes there are two brachial arteries. One in each arm.
