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.
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.
Radial
Artery
Branches of Radial Artery
 Muscular branches
 Recurrent branch
 Superficial Palmar branch
 Joins ulnar artery to
complete the Superficial
Palmar Arch
 Radialis Indicis artery
 Princeps Pollicis
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.
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
Ulnar
Artery
Ulnar
Artery
Branches
Areas of
Ulnar
&
Radial
Arteries
Supply
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
Deep
Palmar
Arch
Superficial Palmar Arch
 Direct continuation of Ulnar artery.
 Superficially placed in palm in front of the long flexor
tendons.
 The Arch on lateral side is completed by superficial
palmar branch of the radial artery.
 Branches: Four digital arteries
Superficial
Palmar
Arch
Areas of Upper
Limb Arteries
Pulsation
Veins of the Upper Limb
 Superficial veins
 Deep veins
Veins of
the Upper
Limb
Superficial Veins of the Upper Limb
 Dorsal venous arch
 Veins of the Palm
 Cephalic vein
 Basilic vein
 Median vein of the forearm
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
Dorsal
Venous
Arch
Dorsal venous arch
Veins of the Palm
 Superficial palmar venous Arch
 Deep palmar venous Arch
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
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.
Cephalic Vein
Cephalic Vein
Cephalic
Vein
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
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
Median Cubital Vein
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)
Median Vein of the Forearm
Deep Veins of the Upper Limb
 Venae Comitantes
 Axillary vein
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
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
Axillary
Vein
Superficial and Deep veins of the Limb
Varicose
veins
