Great vessels Flashcards
Describe order of upper limb venous structures
Medial to lateral
A=abdomen, B =Basilic, C=Cephalic
Where does common carotid artery bifurcate?
C4
What are pulmonary and systemic blood pressure?
20/10
120/80
What are the upper limb pulses you can feel?
Axillary artery (axilla) Brachial artery (medial to biceps tendon at cubital fossa) Ulnar and radial pulse
What are the pulses of the lower limb?
Femoral artery pulse (midinguinal point)
Popliteal artery (back of knee)
Posterior tibial artery (medial malleolus)
Dorsalis pedis artery (top of foot)
Describe 3 components of aorta?
Ascending
Aortic arch
Descending
What is the first structure to come off the ascending aorta?
Right and left coronary arteries
What structures come of the aortic arch?
Brachiocephalic vein
Left common carotid and left subclavian
What becomes of the brachiocephalic artery?
Right common carotid artery and right subclavian artery
What does subclavian arteries supply?
Upper limbs and parts of neck and chest wall (via anterior intercostal arteries)
What does descending thoracic aorta do?
Midline branches to bronchi and oesophagus (bronchial, oesophageal)
Segmental posterior intercostal arteries to chest wall
At what level does descending aorta divide?
L4
Is descending aorta to left or right of IVC?
Left
What level does IVC reform?
L5
What level do renal arteries come off?
L1
Describe arterial supply to head and neck
Left and right common carotid arteries each divide into internal and external carotid arteries
What do external carotid arteries branch off to?
Thyroid and facial artery
What is the difference between internal and external carotid?
Internal carotid has no branches in neck before it reaches skull
Where does vertebral artery branch off from, what does it supply?
Branch of subclavian.
Two vertebral arteries merge to form basilar artery which joins circle of Willis, supply posterior parts of the brain
Describe the branches of the abdominal aorta
Coeliac artery to foregut (arises at T12)
Superior mesenteric artery arises at L1/2
Inferior mesenteric artery to hindgut (arises at L3)
Describe how aorta divides in pelvic region
Divides to right and left common iliac artery at L4
What happens to each common iliac artery?
Bifurcates to external iliac artery and internal iliac artery
What happens to external iliac artery?
Passes under inguinal ligament to become femoral artery (supply lower limb)
What happens to internal iliac arteries?
Supply pelvic organs and gluteal regions (gives off superior and inferior gluteal arteries)
