The anterior intercostal veins originate from the intercostal space just inferior to anterior aspects of their respective ribs and drain into the internal thoracic and musculophrenic veins.

Where does the first intercostal vein drain into?

brachiocephalic vein
The 1st posterior intercostal vein, supreme intercostal vein, drains into the brachiocephalic vein or the vertebral vein.

Where is the main intercostal neurovascular bundle located?

The neurovascular bundle, located in the costal groove in the undersurface of each rib, between the internal intercostal muscle and innermost intercostal muscle, supplies much of the innervation and vascular supply to the thoracic wall.

How do you feel intercostal spaces?

From the angle of Louis, move your fingers to the right and you will feel a gap between the ribs. This gap is the 2nd Intercostal space. From this position, run your fingers downward across the next rib, and the next one. The space you are in is the 4th intercostal space.

Can you feel the first intercostal space?

Anteriorly, the first rib cannot be palpated below the clavicle, but the first intercostal space may be felt above the second rib. The position of the second rib is a reliable landmark anteriorly for determining the position of other ribs: palpate down the manubrium to the manubrio-sternal junction.
