Which artery is found behind the medial border of the coracobrachialis muscle?

The artery that is located behind the medial border of the coracobrachialis muscle is the axillary artery. This artery plays a crucial role in supplying blood to the upper limb and is an important continuation of the subclavian artery as it passes into the arm.

The axillary artery is positioned in such a way that it runs posterior to the coracobrachialis muscle, which is an important muscle in the front of the upper arm responsible for flexing and adducting the arm at the shoulder. Understanding the anatomical relationship between the axillary artery and the coracobrachialis muscle aids in various clinical considerations and surgical approaches to the shoulder and upper arm.

In contrast, the other arteries mentioned do not have the same anatomical context with respect to the coracobrachialis. The brachial artery, for example, runs more distally in the arm and does not correlate with the position behind the medial border of the coracobrachialis. The radial artery is found more lateral as it travels down the forearm, and the subclavian artery is located more proximally before it transitions into the axillary artery, not positioned behind the coracobrachialis muscle.

This anatomical knowledge is vital for professionals who work
