It gives branches to the muscles of the anterior compartment. The artery is in between the median nerve and the tendon of the biceps muscle in the cubital fossa. It then continues into the forearm. The deep artery of the arm travels through the lower triangular space with the radial nerve. From here onwards it has an intimate relationship with ...

When this muscle contracts, normally the arm moves due to having less mass than the torso.
