18
Radial Artery

• Smaller terminal branch of Brachial artery.
• Begins in the cubital fossa passes below
  Brachioradialis muscle.
• Rest on deep muscles of forearm.
• In the distal part of forearm it lies on anterior
  surface of the Radius.

19
Radial Artery

• At wrist it winds backward and passes anteriorly
  into the palm between two heads of 1st dorsal
  interossei muscle.
• Then it joins deep branch of ulnar artery to form
  Deep Palmar Arch.

20
Radial Artery
21
Branches of Radial Artery

• Muscular branches
• Recurrent branch
• Superficial Palmar branch
• Joins ulnar artery to form Superficial Palmar
  Arch
• Radialis Indicis artery
• Princeps Pollicis

22
Ulnar Artery

• Larger terminal branch of Brachial artery.
• Begins in the cubital fossa descends through
  anterior compartment of forearm.
• It enters the palm in front of flexor
  retinaculum.
• It ends by forming Superficial Palmar Arch with
  Superficial Palmar branch of Radial artery.

23
Branches of Ulnar Artery

• Muscular branches
• Recurrent branches
• Deep Palmar branch
• Joins radial artery to form Deep Palmar Arch
• Common Interosseous artery
• Anterior Interosseous artery
• Posterior Interosseous artery

Deep Palmar Arch

• Direct continuation of Radial artery.
• Deeply placed in palm in front of the metacarpal
  bones Interosseous muscles.
• The Arch on medial side is completed by deep
  branch of the ulnar artery.
• Branches Palmar, Metacarpal, Perforating
  Recurrent

28

Superficial Palmar Arch

• Direct continuation of Ulnar artery.
• Superficially placed in palm in front of the long
  flexor tendons.

Veins of the Upper Limb

• Superficial veins
• Deep veins

35
Veins of the Upper Limb
36
Superficial Veins of the Upper Limb

• Dorsal venous arch
• Veins of the Palm
• Cephalic vein
• Basilic vein
• Median vein of the forearm

37
Dorsal venous arch

• Lies in the subcutaneous tissue proximal to
  Metacarpophalangeal joints
• Drains on the lateral side into the Cephalic vein
• Drains on the medial side into the Basilic vein
• Communicates with the deep veins of the palm
  freely

38
Dorsal Venous Arch

Dorsal venous arch
40
Veins of the Palm

• Superficial palmar venous Arch
• Deep palmar venous Arch

41
Cephalic Vein

• Arises from the lateral side of the dorsal venous
  arch on the back of hand.
• Winds round the lateral border of forearm
• Ascends in the superficial fascia into the
  cubital fossa and up the front of the arm on the
  lateral side of Biceps

42
Cephalic Vein

• On reaching the interval between deltoid
  Pectoralis major muscles, it pierces deep fascia
  joins the Axillary vein.
• Drains the lateral and posterior surfaces of the
  limb.
• Median Cubital Vein, a branch of cephalic vein,
  joins the Basilic vein in the cubital fossa.

Basilic Vein

• Arises from the medial side of the dorsal venous
  arch on the back of hand
• Winds round the medial border of forearm
• Ascends in the superficial fascia on the
  posterior surface of the forearm
• Below elbow it inclines to reach the cubital fossa

47
Basilic Vein

• Ascends on the medial side of Biceps
• It pierces deep fascia at the middle of the arm
• It joins the vena comitantes of the brachial
  artery to form the Axillary vein.
• Drains the medial and posterior surfaces of the
  limb.
• Receives Median Cubital Vein at cubital fossa.

Basilic Vein
49
Median Cubital Vein
50
Median Vein of the Forearm

• Arises in the palm
• Ascends on the front of forearm
• Drains into Basilic vein or Median cubital vein
  or divides into two branches
• Median Basilic vein (Drain into basilic vein)
• Median cephalic vein (Drain into cephalic vein)

51
Median Vein of the Forearm
52
Deep Veins of the Upper Limb

• Venae Comitantes
• Axillary vein

53
Vena Comitantes

• Deep veins accompany the respective arteries as
  vena comitantes
• Two vena comitantes of brachial artery join the
  basilic vein at the lower border of teres major
  to form Axillary vein

54
Axillary Vein

• Formed by the union of the vena comitantes of
  brachial artery with basilic vein
• It becomes Subclavian Vein at the outer border of
  1st rib
• Tributaries correspond to the branches of the
  axillary artery and also receive Cephalic Vein
