- Discussion:
- subscapular artery is usually largest branch of
Axillary Artery
and arises from the 3rd part of the artery;
- branches of subscapular artery enter costal surface of
Subscapularis
muscle, & frequently one or more small twigs arising directly from
Axillary Artery do likewise;
- from its origin it typically passes backward and divides into 2 trunks
- scapular circumflex artery
- passes around lateral border of scapula between scapula & teres
major (in
trianglular space );
- it turns upward between
Infraspinatus
& scapula to supply
this muscle and anastomose w/ suprascapular artery & deep
branch of the transverse cervical artery;
