Correct answer: B — Supraspinatus and infraspinatus
The suprascapular nerve (C5-C6) arises from the upper trunk and passes through the suprascapular notch (under the superior transverse scapular ligament). It innervates supraspinatus (abduction initiation 0-15°) and infraspinatus (external rotation). Suprascapular nerve block provides analgesia for shoulder surgery.
