Arteries supplying the upper limb
Subclavian artery
BRACHIAL ARTERY
. Superficial & deep palmar arches
Deep palmar arch arise mainly from the radial artery
Superficial palmar arch mainly from the ulnar artery
Rt) subclavian artery arises from
the brachiocephalic artery
Lt) subclavian artery arises
directly from the aortic arch
The subclavian artery runs
laterally between the clavicle & 1st rib to enter the axilla.
Subclavian artery leaves
the lateral border of the 1st rib and enters the axilla where is called the * Axillary artery
Axillary artery sends branches and continues as
brachial artery in upper arm
Brachial artery splits into
radial & *ulnar arteries
Brachial artery splits at
the elbow joint ( cubital fossa)
Axillary A. becomes Brachial A.
at the lower border of teres major muscle
Brachial A. passes through
the middle side of the arm accompanied with the median nerve, until it reaches the
cubital fossa where it’s divided to radial artery and ulnar A.
Scapular anastomosis is formed by
- Dorsal Scapular artery
- Supracapular artery
- Circumflex Scapular
Dorsal Scapular artery branch of
transverse cervical art
transverse cervical art is
Subclavian art
Suprascapular artery branch of
thyrocervical trunk
thyrocervical trunk is
Subclavian art
Circumflex Scapular branch of
subscapular artery
subscapular artery
Axillary art
Scapular anastomosis is
System connecting the subclavian artery and axillary artery forming a circulatory anastomosis around the scapula
brachial artery branches to give radial A at
the upper end of the radius
radial A runs at
the lateral side of the forearm
inferolaterally under cover of brachioradialis muscle
→ Then it lies lateral to flexor carpi radialis tendon in distal forearm → finally it winds around lateral aspect of radius and crosses the floor of anatomical snuff box to pass
between the two heads of first dorsal interosseous muscle. It ends by taking
part in the formation of the deep palmar arch of hand
brachial artery branches to give ulnar A.
below the flexion of the elbow
ulnar artery branches
common interosseous artery
common interosseous artery is divided to
anterior and posterior interosseous artery.
ulnar A. and radial A مين اطول
Ulnar artery is longer and larger than the radial A
Deep palmar arch arise mainly from
the radial artery
Superficial palmar arch mainly from
the ulnar artery
The arches are formed by
an anastomosis of the radial & ulnar arteries in the palm of the hand
The metacarpal arteries arise from
the deep palmar arch
The digital arteries arise from
the superficial palmar arch
every finger has
two digital arteries (left & right)
Descending Aorta
Thoracic aorta
Abdominal aorta
Thoracic aorta at
T12 becomes abdominal aorta
Abdominal aorta ends at
L4
Abdominal aorta divided into
R & L common iliac arteries at L4
median sacral .A s
Branches of Thoracic aorta
- Posterior intercostal branches
- Pericardial branches
- Oesophageal branches
- Bronchial branches
- superior phrenic arteries
Branches of the abdominal aorta
- Anterior, midline branches
- Paired branches from the side of abdominal aorta
- paired branches from behind of abdominal aorta
- Terminal branches
Anterior, midline branches of the abdominal aorta supply
digestive tube :
Celiac trunk
Superior mesenteric artery
Inferior mesenteric artery
Paired branches from the side of abdominal aorta
Inferior Phrenic arteries
adrenal arteries,
Renal arteries
Gonadal arteries
paired branches from behind of abdominal aorta
Four lumbar arteries
Terminal branches
Right and left common iliac arteries
R & L common iliac arteries divided inton
External iliac artery
Internal iliac artery
External iliac artery supplies
the remaining of lower limb
Internal iliac artery supplies
the pelvic organs, perineum , buttocks and medial thighs
External iliac artery passes
underneath the inguinal ligament
External iliac artery becoming
Femoral artery in front of the thigh
Femoral artery called the popliteal artery after passing through
behind the thigh Through the adductor canal (hiatus), runs through the popliteal fossa
the femoral artery becomes
popliteal artery,
the femoral artery becomes popliteal artery, at
back of knee
Popliteal artery Is the continuation of
the femoral artery
Popliteal artery ends at
the lower border of the popliteus muscle by dividing its terminal branches
Popliteal artery dividing into its terminal branches
1- The Anterior tibial artery
2- Posterior tibial artery
Posterior tibial artery which gives the
peroneal artery *) febular artery )
Anterior Tibial Artery Supplies
all structures in the anterior compartment of the leg and gives perforating branches to lateral compartment
Anterior Tibial Artery enters
the foot at the midpoint between the malleoli.
Anterior Tibial Artery On the foot it continues as
Drorsalis Pedis Artery
Drorsalis Pedis Artery pass
between the 1st and 2nd metatarsal bones
reaching the sole of the foot as deep planter artery
Posterior Tibial Artery supplies
all structures in the posterior compartment of the leg
Posterior Tibial Artery gives
Peroneal artery
Peroneal artery
the posterior and lateral compartments of the leg.
Post. Tibial artery runs
behind and inferior to medial malleolus
It then enters the sole of the foot
Post. Tibial artery divides
into
Medial and Lateral plantar branchesلما
enters the sole of the foot
Deep plantar arch
Deep plantar arch is formed by
the deep plantar branch of dorsalis pedis artery and lateral plantar artery
