This is my first post on this site and I apologize if it's in the wrong forum section, I'm just very much in a hurry and didn't get to browse the website fully.

I am studying for my final tomorrow in A&P, it's a visual exam. We have pictures of almost every organ and will have to label them correctly. Problem is, my copy of the heart has the right side cut out. Regardless, I know all of them but two. The very top artery, on right side of the heart, not the left common carotid or the subclavian, but the other. From what wasn't cut out it reads "achiocephalic artery". Second is an artery towards the bottom, I'm pretty sure it's the Marginal Artery, as my paper reads "arginal Artery". Im just double checking on that one. Any help for the top one would really help me.

Thanks in advance!

The big top one is the brachiocephalic (trunk) artery
