Where does the Musculophrenic artery run around?
What does it supply?
Run around: the costal margin of the diaphragm.
Supply:7th-9th intercostal spaces and diaphragm
(bc the pharynx is technically connected to the dipharagm )
What is the Coarctation of the aorta? What is the cardinal clincal (diagnosis) sign?
What is a identification point of it in an xray picture?
It is congenital narrowing in the aorta just after the left subclavian artery branches
Diagnosis: Higher blood pressure in the upper limbs than lower limbs (bc of the fact that the heart has to push harder)
Xray: serrated appearance of inferior borders of ribs (rib notching)
What is collateral circulation?
The intercostal arteries provide an alternate route for blood flow between the internal thoracic artery and the thoracic aorta to provide blood supply to the lower body.
