LAB QUIZ NOTES Branches of the lateral cord Lateralpectoral nerve Musculocutaneousnerve Lateralroot of median nerve Branches of the medial cord Medialpectoral nerve Medialcutaneous nerve of arm Medialcutaneous nerve of forearm(medial antebrachial cutaneous nerve) Ulnar nerve Median nerve Branches of the posterior cord Superior subscapular nerve Thoracodorsal nerve Inferior subscapular nerve Axillary nerve Radial nerve

  4. IV.COMMITTEE I. LAB QUIZ NOTES Table 1. Extrinsic back muscles [Superficial (appendicular) group & intermediate (respiratory) group of back muscles]

  5. Table 2. Muscles of the arm IV.COMMITTEE I. LAB QUIZ NOTES

  6. IV.COMMITTEE I. LAB QUIZ NOTES Table 3. Scapulohumeral (Intrinsic) shoulder muscles Collectively, the supraspinatus, infraspinatus, teres minor, and subscapularis muscles are referred to as the rotator cuff, or SITS, muscles. Their primary function during all movements of the glenohumeral (shoulder) joint is to hold the humeral head in the glenoid cavity of the scapula.
