How does the suprascapular artery course after its origin?
Travels laterally, roughly parallel to the clavicle, crosses over the suprascapular notch, and travels deep to the supraspinatus muscle.
p.1
Scapular Anastomosis Anatomy
How does the circumflex scapular artery course?

p.1
Scapular Anastomosis Anatomy
Where does the dorsal scapular artery travel after originating from the subclavian artery?
Laterally and posteriorly through the trunks of the brachial plexus to the superior angle of the scapula.
p.4
Site of venipuncture, intravenous feeding and venous cutdown
What is venous cutdown?
An emergency procedure where a vein is exposed surgically, followed by cannula insertion under direct vision.

Collateral circulation in upper limbs
What does the FCR tendon refer to?
Flexor carpi radialis tendon, which helps in wrist flexion.
p.2
Collateral circulation in upper limbs
What is the significance of the scapular anastomosis?
It allows blood to flow from the subclavian artery to the third part of the axillary artery when the axillary artery is ligated or occluded above the origin of the subscapular artery.
