Which arteries does not branch directly off the aortic arch?
The arteries that do not branch directly off the aortic arch include the subclavian arteries and the internal thoracic arteries. Instead, the subclavian arteries arise from the brachiocephalic trunk (on the right side) or directly from the arch of the aorta (on the left side). The internal thoracic arteries branch off the subclavian arteries, further indicating they do not stem directly from the aortic arch.

The brachiocephalic trunk is a major artery that branches off from the aortic arch, supplying blood to the right arm, head, and neck. It is only present on the right side of the body because the left subclavian and left common carotid arteries branch directly off the aortic arch, eliminating the need for a separate brachiocephalic trunk on the left side.
