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

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

superficial lymphatics found:

A

skin and subcutaneous tissue

29
Q

deep lymphatic vessels:

A

accompany deep arteries and veins

30
Q

superficial and deep lymphatics drain into lymphatic trunks:

A
  • lumbar,
  • intestinal,
  • bronchomediastinal
  • subclavian
  • jugular
31
Q

lymphatic trunks drain into:

A

thoracic duct, right lymphatic duct

32
Q

what drains into thoracic duct:

A

body inferior to diaphragm and LHS body superior to diaphragm.
- from L2 -> left subclavian vein

33
Q

what drains into right lymphatic duct:

A

all right side superior to diaphragm.

- into right subclavian vein

34
Q

main lymph nodes (7):

A
  • cervical
  • axillary
  • popliteal
  • inguinal
  • thoracic
  • abdominal
  • GIT
35
Q

list first 3 axillary groups of lymph nodes

A
  • pectoral
  • subscapular
  • humeral
36
Q

lymph node: pectoral

A

medial wall: drain anterior thoracic wall, breast

37
Q

lymph node: subscapular

A

posterior: drain posterior thorax and scapula

38
Q

lymph node: humeral

A

lateral wall: drains upper limb except vessels near cephalic vein

39
Q

first 3 lymph nodes drain into:

A
  • central: deep to pec major

then-
- apical: drains vessels around cephalic vein

40
Q

apical lymph nodes drain to:

A

subclavian lymphatic trunks - right lymphatic duct and thoracic duct

41
Q

right apical nodes to:

A

R subclavian trunk - right lymphatic duct. joins blood vessels at junction of R subclavian and R internal jugular veins at root of neck

42
Q

left apical nodes to:

A

L subclavian trunk - thoracic duct at base of neck. joins blood vessels at junction of L subclavian and L internal jugular veins at root of neck

43
Q

most imaging of upper limb blood vessels via: function

A

ultrasound:

  • detects anatomical variants
  • can measure blood flow
44
Q

angiography:

A

also performed:

- x-ray of blood vessels seen through injection of dye to outline vessels on x-ray
