46
Q

Arterial supply to hand

A

Radial + ulnar artery supply hand via deep + superficial palmar arches

47
Q

Where can you palpate the ulnar artery?

A

Anterior to flexor retinaculum
Lateral to pisiform bone + ulnar nerve

48
Q

Explain the arterial supply to the hand

A
  • Radial and ulnar artery branch into deep and superficial branches
  • The corresponding deep or superficial artery anatomy’s to produced the deep + superficial palmar arches
  • Superficial palmar artery gives off common palmar digital arteries - supply fingers
  • Deep palmar artery supplies radial index finger + thumb
49
Q

What’s the blood supply to the fingers?

A

Common digital arteries from superficial palmar arch

50
Q

What’s the blood supply to the thumb and radial index finer?

A

Deep palmar arch

51
Q

What is the main contribution of the ulnar artery?

A

Supplies fingers
Via common palmar digital arteries

52
Q

What is the main contribution of the radial artery?

A

Supplies thumb + radial index finger
Via deep palmar arch

53
Q

What is the main contribution to the fingers/

A

Ulnar artery
Via common palmar digital arteries

54
Q

What is the main contribution to the thumb and radial index finger?

A

Radial artery
Via deep palmar arch
