The outer border of the first rib manage the axillary artery which is the extension of the subclavian artery and three parts of the course of the axillary artery leads to this outer border. Axillary artery has six branches where branches of subclavian and axillary arteries around the scapula have extensive collateral circulation which is associated with them lead to variations in the branching pattern. Two procedures, classical incisions and dissection lead to achieve the exposure of axillary artery and its branches in 50 upper limbs of 25 cadavers including 20 males & 5 females. One specimen showed the anomalous branching of the axillary artery with the successful observation which results in the dividing of axillary artery of right upper limb into superficial brachial and deep brachial arteries. The axillary artery has branching pattern which was normal on the left side. The arterial system of the upper limb has variations which are well documented. On the basis of embryologic development of the vascular plexuses of the limb buds, the variations and anomalies of the arterial system to the upper limb can be explained best. A model has been proposed which demonstrates the development of the arteries of upper limb in 5 stages. This model explains the development of an axial system appears first and other branches develop later from this axial system. Charles et al, year 1931 specify 7 Types of origins for this artery where the origin of arteria profunda brachii is quite variable in 54.7% cases. In case of surgeons the sound knowledge of axillary artery variation plays important role because the axillary artery is more common lacerated by violence.
