Lecture 22. Circulatory system III Flashcards
Where is the axillary artery located
axillary fossa
What gives rise to the axillary artery
subclavian artery
What do the branches of the axillary
supply the muscular walls of axilla
When does the axilla become a brachial artery
inferior border of teres muscle
What supplies the anterior and posterior aspect of the arm
anterior: brachial artery
posterior: branch of the brachial artery- deep brachial artery
what are the terminal branches of the brachial artery
radial (lateral side) and ulnar (medial) branches
What gives rise the palmar arches
ulnar and radial arteries
What does the superficial and deep palmar arch supply
supplies the palm ( and less accurately fingers)
What does supplies the fingers
digital arteries
What does the descending aorta divide into
thoracic and abdominal aorta
how is the thoracic aorta divided?
- parietal group : supplies wall of the thorax
2. visceral group: supplies to the viscera
how is the abdominal aorta divided?
- parietal branches: supplies wall of the abdomen
2. visceral group: supplies the viscera (eg. celiac artery)
The end point of descending aorta is ?
4th lumbar vertebrae
Where is the starting point for descending aorta?
T4-T5 intervertebral disc
What are the terminal branches of the abdominal aorta
left and right common iliac arteries
How does the iliac arteries divide
they split into internal and external iliac arteries at the level of L4
What are the branches of the internal iliac artery
- parietal branch
2. visceral branch: supply pelvic viscera
What does the external iliac artery give rise to
femoral artery at the inguinal ligament
Describe the femoral artery
has an indirect branch called the deep femoral artery that supplies the posterior muscles of the thigh, the femoral artery itself supplies the anterior portion of the leg
Describe what the femoral artery gives rise to after passing through the kneecap, in anterior or posterior?
posterior, the popliteal artery forms.
What are the branches following the popliteal artery
- anterior tibial artery would supply anterior compartment of the leg
- posterior and lateral compartment of the leg would be supplied by the posterior tibial artery
What follows the anterior tibial artery
dorsalis pedis artery
What follows the posterior and tibial artery
medial and lateral plantar arteries
are superficial veins named similarly to arteries
NO only deep veins are
what are the 2 branches of the dorsal venous plexus
cephalic branch- lateral side
basilic- medial side
What forms when the cephalic and basilic veins
median cubital vein
What forms the axillary vein
brachial and basilic form the axillary vein
What do the plantar and venous arches at the toe give rise to ( in terms of superficial veins)
gives rise to the small saphenous that drains to the popliteal vein, on the medial side the great saphenous vein which drains into the femoral vein
What forms teh superior vena cava
internal jugular and subclavian veins
What is the azygus vein
drains all the intercoastal spaces, receives the parietal vein, it drains to superior vena cava
What forms the inferior vena cava
left and right common iliac veins
What forms the portal vein
- splenic vein: drains from the spleen, stomach and pancrease
- inferior mesenteric: large intestine
- superior mesenteric: small intestine
What happens when the portal system is constricted
blood pressure in the portal system causes more blood to be accepted near the esophagus and the anal region
