Question

Major branches of the subclavian artery include the ________ artery(ies).
A) radial
B) brachial
C) internal thoracic
D) digital
E) phrenic

Accepted Answer

The major branches of the subclavian artery include the internal thoracic artery, vertebral artery, thyrocervical trunk, and costocervical trunk. Of these, only the internal thoracic artery is listed as a choice, making C the correct answer. The other options (radial, brachial, digital, and phrenic) are all arteries that arise from other vessels in the upper limb or thorax, and are not direct branches of the subclavian artery.
