Axillary artery Continuation of the
subclavian artery.• Begins at the outer border
of the first rib.• Ends at lower border of
teres major. • Continue as brachial
artery.
Crossed by pectoralis minor, dividing it into three parts.
Each part gives branches according its number.
Located inside axillary sheath and related directly to cords of brachial plexus throughout its course.

Superficial Veins
Both Upper and Lower limb are similar in having two superficial veins to drain their superficial structures.
In the upper limb:
• Cephalic vein Lateral
• Basilic vein Medial
Both ends into the axillary vein.
Both connected by the median cubital veinanterior to elbow joint.• This vein commonly used
to give fluids or to obtain blood sample.
