Document Summary
Axillary nerve abduction of arm (up to 90 degrees); adducts flexes, medially rotates arm, lateral rotation abductor of arm. Suprascapular nerve belongs to rotator cuff muscle group lateral rotator of arm, rotator cuff muscle. Suprascapular nerve lateral rotator of arm rotator cuff muscle. Lower subscapular nerve medial rotation, extension, adduction of arm, Adduction and medial rotation, lowers arm lateral and medial pectoral nerves; flexor of upper arm, assists in respiration originating from the lateral and medial cord of brachial plexus. Biceps brachii rotation of scapula so gleniod faces downward. Long thoracic nerve scapula, holding against thoracic wall, rotating scapula laterally to elevate arm so the glenoid faces upward, lifts ribs flexor of shoulder joint, strong supinator of. Musculocutaneous nerve, forearm, shorthead is an adductor of the arm branching from the lateral cord of brachial p. Musculocutaneous & radial nerve antevertor of the arm. Radial nerve aids in retroversion and adduction of the arm.
