 Profunda Brachii artery
 Superior ulnar collateral artery
 Inferior ulnar collateral artery
 Branches from Ulnar and Radial Arteries:
 Radial & ulnar recurrent arteries

Anastomosis around elbow joint
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.
Branches of Radial Artery
 Muscular branches
 Recurrent branch
 Superficial Palmar branch
Joins ulnar artery to form
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
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
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
