31

Injury to Dorsal scapular nerve

retraction of the scapula on affected side will be weakened

teres major, gravity (depending on body position),
lowest fibers of the deltoid (making deltoid its own antagonist)

Trapezius (scapular rotation, accesory n) (90+)
Serratus anterior (long transverse n) (90+)

39

Fracture of surgical neck of humerus or inferior dislocation, what nerve and artery

axillary posterior humeral circumflex

40

Fracture of humerus, and effects on lateral rotation of the arm

injury to axillary nerve, and lateral rotation would be suprascapularis, infrascapularis, teres minor, and deltoid. BUT suprascapularis and infrascapularis are innervated by the supraspinatus nerveso they will still function, but not teres minor and deltoid

41

46

What creates the anastomoses around the scapula?

circumflex humeral, dorsal scapular, suprascapular artery

Additionally, if the subclavian or axillary artery needs to be ligated, blood can flow from the dorsal scapular artery and suprascapular artery to the circumflex scapular artery

47

Injury to Upper Roots of Brachial Plexus

Erb-Duchenne Palsy. It affects especially the suprascapular, axillary, and musculocutaneous nerves, which causes paralysis of the rotator cuff muscles, biceps, brachialis, coracobrachialis, and deltoid.
upper and lower subscapular nerves, denervating subscapularis and teres major.
lateral pectoral nerve, but the majority of pect major is innervated by medial pectoral nerve, so it is only weakened (can still flex).
the limb is constantly adducted and medially rotated.
the limb can no longer be abducted because both supraspinatus, which initiates abduction, and deltoid, which allows for complete abduction, have been denervated.

48

Cephalic, Basilic, and Median cubital vein

Cephalic runs through deltopectoral groove/triangle on the radial/lateral/thumb side of the arm. Basilic vein runs under the arm on the medial/pinky/ulnar side of the arm. Median cubital vein connects these two

49

Branches of the Axillary Arter

1- superior thoracic artery (think #1is the best, so superior)
2- thoracoacromial and lateral thoracic (think: 2 times thorac.
3- subscapular, posterior and anterior humeral circumflex (think: three is the lowest, so it is SUB.)

50

What is the branch of the musculocutaneous nerve and what does it do?

lateral antebrachial cutaneous n. (think muscuLAcutaneous. LA. lateral antebrachial). innervation of lateral part of the forarm

51

fracture to the surgical neck of the humerus

The posterior and anterior circumflex arteries wrap around the humerus near its surgical neck.

Subscapularis (medial rotation,upper subscapularis)

56
