Meaning and Definition
The major artery originating from the aortic arch that supplies blood to the right arm and the head.
In anatomical contexts, it refers specifically to the first and largest branch from the aortic arch, which subsequently divides into the right common carotid artery and the right subclavian artery. In some individuals, it may also give rise to the thyroid ima artery.
Dialectal Variation
British vs American Usage
Differences
No lexical difference. In British anatomical texts, the term 'innominate artery' is used interchangeably as a synonym. American texts primarily use 'brachiocephalic artery', though 'innominate artery' is also understood.
Connotations
Identical technical connotations in both variants.
Frequency
Slightly more frequent in American medical literature. 'Brachiocephalic artery' is the standard term in modern international anatomical nomenclature (Terminologia Anatomica).

FAQ
Frequently Asked Questions
No. In normal human anatomy, there is only one brachiocephalic artery, and it is located on the right side. On the left side, the common carotid and subclavian arteries arise directly from the aortic arch.
The brachiocephalic artery is a single artery carrying oxygenated blood from the heart to the right arm and head. The brachiocephalic veins (there are two, left and right) are large veins that carry deoxygenated blood from the head and arms back to the heart.
'Innominate' means 'unnamed'. Historically, before modern anatomical naming conventions, this artery was considered a single trunk without a specific name, simply the 'unnamed artery' branching to the arm and head. 'Brachiocephalic' is now the precise, descriptive term.
A complete, sudden blockage is a life-threatening medical emergency, as it cuts off blood supply to a major part of the brain and the right arm. However, the body can sometimes develop collateral circulation over time if the blockage happens gradually.
The major artery originating from the aortic arch that supplies blood to the right arm and the head.
Brachiocephalic artery is usually formal / academic / medical in register.
Brachiocephalic artery: in British English it is pronounced /ˌbræk.i.əʊ.sɪˈfæl.ɪk ˈɑː.tər.i/, and in American English it is pronounced /ˌbreɪk.i.oʊ.səˈfæl.ɪk ˈɑːr.t̬ɚ.i/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think: BRACHiO (like 'bracelet' for the arm) + CEPHALIC (like 'cephalexin', an antibiotic for the head) + ARTERY = the artery for the arm and head.
Conceptual Metaphor
MAJOR ROAD JUNCTION: The brachiocephalic artery is conceptualized as a major trunk road (from the heart's main highway, the aorta) that splits into two separate routes, one heading to the head (carotid) and one to the arm (subclavian).
