Chapter 21, Problem 12
The two arteries formed by the division of the brachiocephalic trunk are the:
(a) Aorta and internal carotid
(b) Axillary and brachial
(c) External and internal carotid
(d) Common carotid and subclavian
Verified step by step guidance1
Understand the anatomy of the brachiocephalic trunk: it is a major artery branching off the aortic arch on the right side of the body.
Recall that the brachiocephalic trunk divides into two main arteries that supply blood to the right side of the head, neck, and upper limb.
Identify the two arteries formed by this division: one artery supplies the head and neck, and the other supplies the upper limb.
Recognize that the artery supplying the head and neck is the common carotid artery, which later divides into the internal and external carotid arteries.
Recognize that the artery supplying the upper limb is the subclavian artery; therefore, the two arteries formed by the brachiocephalic trunk are the common carotid and subclavian arteries.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Brachiocephalic Trunk Anatomy
The brachiocephalic trunk is a major artery branching from the aortic arch. It is unique because it divides into two main arteries that supply blood to the right side of the head, neck, and upper limb. Understanding its anatomy is essential to identify its branches correctly.

Branches of the Brachiocephalic Trunk
The brachiocephalic trunk divides into the right common carotid artery and the right subclavian artery. The common carotid artery supplies the head and neck, while the subclavian artery supplies the upper limb. Recognizing these branches helps distinguish them from other arteries.

Distinction Between Carotid Arteries
The common carotid artery further divides into the internal and external carotid arteries, which supply different regions of the head. However, these are not direct branches of the brachiocephalic trunk but of the common carotid artery. This distinction is important to avoid confusion in artery identification.
