• It is continuation of AXILLARY artery. It extend from the lower
border of the teres major to a point in front of the elbow at the
level of neck of radius.
• Branches:
• Muscular branches
• Profonda brachii
• Superior ulnar collateral
• Nutritional
• Inferior ulnar collatera
• Two terminal branches ( Radial & Ulnar )
Radial Nerve
It is largest branch of the posterior cord
Branches: Before entering the Radial Groove:
