What is a fossa

Where do the collateral ones (more minor than the main arteries veins and nerves) sit
Sit above the rib below
Where do the internal thoracic artery and vein sit
Sits on either side of the sternum
What do the thoracic arteries branch into
Anterior intercostal arteries
Where does the phrenic nerve pass through
Comes from neck (C3,4,5) Goes through superior mediastinum Middle part of inferior mediastinum Goes close to root of the lung Passes behind the heart Innervates the diaphragm
