Anatomy of suprascapular nerve and surrounding structures

Note that the suprascapular nerve crosses deep to the superior transverse scapular ligament at the superior scapular (or suprascapular) notch (superior yellow circle), while the vessels cross superior to the ligament. After traversing the suprascapular fossa, the neurovascular structures course through the spinoglenoid notch (inferior yellow circle) and head medially along the inferior border of the scapular spine.
