artery

1. NAME : NUR FARRA NAJWA
MATRIC NUM : 082015100035

2. OBJECTIVE
• Beginning of artery
• Course of artery
• Branches of artery
• Anastomosis of artery

3. INTRODUCTION
• Smaller artery of the terminal branches of
brachial artery
• Begins at the cubittal fossa at the level of the
neck of the radius

6. COURSE
• Passed downwards and laterally beneath
brachioradialis muscle
• Resting on the deep muscle of fore arm
• On its middle third the radial nerve lies lateral
sides
• Distal fore arm : lies anterior surface of radius
: only covered by skin fascia
: here artery lateral side
(tendon brachioradialis)
medial sides (flexor carpi radialis)

7. COURSE
• Leave fore arm by winding lateral aspect of
wrist to reach posterior of the hand.
Beneath tendon abductor pollicis longus and
extensor pollicis brevis
Lie on lateral ligament of joint
• on reaching dorsum
descends beneath extensor pollicis longus
Reach 2 heads of forst dorsal interosseous muscle
Artery turn forwards entering palm of hand

8. Branches of Radial Artery
• Radial recurrent artery
– Arises below the elbow
– Run upward deep into brachioradialis
– Anastomosing with radial collateral artery (branches
of profunda brachii artery)
• Dorsal carpal branch
– Forms dorsal carpal arch with branch of ulnar artery
• Muscular branches
– Given to the lateral muscle of forearm

9. • Palmar carpal branch
– Arises near lower border of the pronator
quadratus
– Run medially deep to the flexor tendon
– End by anastomosing with the palmar carpal
branch of ulnar artery.
• Superficial carpal branch
– Arises just before the radial artery leaves the
forearm by winding backwards.
– Passes through the thenar muscle
– Ends by joining the terminal part of the ulnar
artery to complete superficial palmar arch.

11. ANASTOMOSIS

12. DEEP PALMAR ARCH
• Direct continuation of radial artery
• Medially curve beneath long flexor tendon, in front of the
metacarpal bone and interroseous muscle
• Arch completed on medial side by deep branch of ulnar
artery
• Arch curve lies at level with the proximal border of the
extended thumb
• Send branches
a) Superiorly : taking part of anastomosis along wrist joint
b) Inferiorly : to joint the digital branches of superficial
palmar arch

14. Clinical Importance of Radial Artery
• Usually uses by the clinician to measure the
radial pulse.
• Radial pulse can be uses to estimate the blood
pressure as it indicate the systolic blood
pressure of at least 70mmHg.
• It also uses for coronary artery bypass
grafting.
