Question

What artery do perforating arteries branch off of?

Answer 1

Perforating arteries branch off from major arteries like the deep brachial artery, descending aorta, inferior epigastric artery, and superior epigastric artery, depending on their location in the body.

Step-by-step explanation:

Perforating arteries can branch off of several larger vessels depending on their location in the body. For instance, in the limbs, the deep brachial artery gives rise to perforating branches that supply the muscles and bones of the arm. In the case of the lower limb, the descending aorta branches out into the likes of femoral arteries, from which perforating arteries could branch further. Additionally, in the abdominal region, the inferior epigastric artery, which is a branch of the external iliac artery, can give off several small perforating branches to supply the abdominal wall. The same concept applies to the thorax, where the superior epigastric artery—a branch of the internal thoracic artery—can also give rise to perforating arteries.
