rn: radial nerve
mn: median nerve

Note: The brachial artery is easily located due to its arterial pulse, the median nerve lies medially to it. The radial nerve lies between the brachioradialis and brachialis muscle. Both nerves can be followed distally - the median nerve to the wrist and the radial nerve to its bifurcation (superficial sensory branch and posterior interosseous nerve).
