29
Q

what do some people have instead of a basilic vein and a cephalic vein

where does it run

A

median vein

up the middle of the forearm

30
Q

what are the 4 superficial veins of the upper arm

A

dorsal venous arch
cephalic vein
basilic vein
median cubital vein

31
Q

where is the median cubital vein

A

cubital fossa

32
Q

where does the basilic vein drain

A

brachial vein

33
Q

where does the cephalic vein drain

A

axillary vein

34
Q

where does the deep venous arch of the hand drain

A

radial vein

35
Q

where does the superficial venous arch of the hand drain

A

ulnar vein

36
Q

where does the dorsal venous arch drain blood from

A

dorsal surface of hand

37
Q

what does the brachial vein drain into

A

axillary vein

38
Q

what does the axillary vein drain into

A

subclavian vein

39
Q

where does the medial dorsal venous arch of the foot drain into

A

great saphenous

40
Q

what drains into the small saphenous

A

lateral dorsal venous arch of the foot

41
Q

where does the great saphenous vein drain

A

femoral vein

42
Q

where does the small saphenous vein drain

A

popliteal

think bc its the ‘small’ saphenous that its smaller that the great saphenous so drains earlier

43
Q

what are the superficial veins of the lower limb (4)

great saphenous
small saphenous
medial dorsal venous arch of the foot

fibular vein

what do the anterior and posterior tibial veins drain into

A

popliteal vein

47
Q

what does the popliteal vein drain into

A

femoral vein

48
Q

what 3 things drain into the popliteal vein

A

anterior tibial vein
posterior tibial vein
small saphenous

49
Q

apart from the popliteal vein, what else drains into the femoral vein (2)

A

deep femoral vein

great saphenous

50
Q

where does the femoral vein drain into

A

external iliac vein

what condition is the perforating veins associated with

A

varicose veins

55
Q

where do all upper limb lymph end up

A

subclavicular lymph nodes

56
Q

what do the lymphatics of the upper limb follow

A

veins

57

A

veins

61
Q

lymphatics that follow the great saphenous vein end up…

A

superficial inguinal lymph nodes (then deep inguinal then external iliac lymph nodes)

62
Q

lymphatics that follow the small saphenous vein end up…

A

popliteal lymph nodes (then deep inguinal then external iliac lymph nodes)

63
