9
Q

axillary major branches: 3rd part

A

subscapular:
posterior axilla wall and posterior scapular region -> divides into circumflex scapular aa, thoracodorsal aa

anterior circumflex humeral + posterior circumflex humeral = anastomose

10

11

12
Q

brachial major branches: radial and middle collateral arteries

A

branches of profunda brachii

13
Q

brachial major branches: superior and inferior ulnar collateral

A

contribute to network around the elbow joint

14
Q

to remember axillary artery branches:

A

Send The Lord To Say A Prayer:

  • superior thoracic
  • thoracoacromial
  • lateral thoracic
  • subscapular
  • anterior circumflex humeral
  • posterior circumflex humeral
15
Q

cords of brachial plexus closely related to which part of axillary artery?

A

2nd part

16
Q

list vessels in cubital fossa:

A
  • brachial artery
  • radial artery
  • ulnar artery

(more info on slide)

17
Q

major arterial branches in forearm: radial

A
  • radial recurrent : anastomosis at elbow, supplies lateral forearm muscles
  • palmar and dorsal carpal branches
  • many ‘muscular arteries’

BEST muscles:

  • brachioradialis
  • extensors
  • supinator
  • triceps
18
Q

major arterial branches in forearm: ulnar

A
  • ulnar recurrent: with anterior and posterior branches, cont to anastomosis around elbow
  • common interosseous: divides into ant/post branches
    JOINS: posterior interosseous (for post com muscles) + anterior interosseous (deep ant and post com)
  • palmar and dorsal carpal branches (forms arches with radial branches of same name)
  • many ‘muscular’ arteries
19
Q

major branches in hand: radial

A
  • superficial palmar branch
  • dorsal carpal branch
  • first dorsal metacarpal artery (supplies adjacent sides of index finger and thumb)
  • princeps pollicis artery (major supply to thumb)
  • radialis indicis artery (for lateral side of index finger from same point of PPA above)
  • deep palmar arch: (3 palmar metacarpal arteries, 3 perforating branches that joint the dorsal metacarpal arteries from the dorsal carpal arch)
20
Q

major branches in hand: ulnar

A
  • superficial palmar arch: palmar digital artery (on medial side of pinky) 3 common palmar digital arteries (joined by palmar metacarpal arteries from deep palmar arch)-> bifurcate into proper palmar digital arteries to the fingers
  • deep palmar branch
21
Q

2 sets of veins:

A

superficial and deep

22
Q

features: superficial veins

A
  • lie in superficial fascia
  • variable pattern
  • do not accompany arteries
23
Q

features: deep veins

A
  • lie deep to deep fascia
  • more valves than superficial veins
  • accompany arteries, usually as PAIRS of veins (venae comitantes)
24
Q

flow of venous drainage from: superficial posterior surface of hand to anterior forearm superficial

A

dorsal digital - dorsal metacarpal - dorsal venous network (dorsal venous arch) - accessory cephalic/ cephalic/ basilic - brachial/ axillary - subclavian

25
Q

flow of venous drainage from: superficial anterior hand and forearm

A

palmar digital - palmar venous plexus - median antebrachial - basilic/ median cubital - brachial - axillary - subclavian

26
Q

flow of venous drainage from: deep veins in anterior surface of forearm, each paired- palmar metacarpal

A

palmar metacarpal - palmar deep venous arch - radial - brachial - axillary - subclavian

27
Q

flow of venous drainage from: deep veins in anterior surface of forearm, each paired- proper palmar digital

A

proper palmar digital - common palmar digital - superficial palmar venous arch - ulnar - brachial - axillary - subclavian

28
Q

A

skin and subcutaneous tissue
