The intercostal veins are a group of veins which drain the area between the ribs ("costae"), called the intercostal space. They can be divided as follows: Anterior intercostal veins; Posterior intercostal veins. Posterior intercost vein that drain into the Supreme intercostal vein - 1st intercostal space
Deleted erroneous label to external pudendal vein. Deleted inferior thyroid vein (Since there are many other veins on the anterior face of the neck of equal importance). Redraw last intercostal veins. Add temporal vein (not labelled). Correct position of superior and inferior epigastric veins. Corrections of arrows of external iliac vein.
The intercostal arteries are a group of arteries passing within an intercostal space (the space between two adjacent ribs). There are 9 anterior and 11 posterior intercostal arteries on each side of the body. The anterior intercostal arteries are branches of the internal thoracic artery and its terminal branch – the musculophrenic artery.
Perforating branches; six anterior intercostal branches. upper branches; lower branches of the space anastomoses; Musculophrenic artery. intercostal branches (three) branches to lower part of the pericardium; branches to diaphragm; branches to abdominal muscles; Superior epigastric artery
The lower branch of the space anastomoses with a collateral branch of the posterior intercostal artery. After passing the sixth intercostal space, the internal thoracic artery splits into the following two terminal branches: Musculophrenic artery – roughly follows the costal margin and it again gives branch for 7,8,9 ribs
This branch is not constant, but is more commonly found on the right side; when absent, its place is supplied by an intercostal branch from the aorta. Each intercostal gives off a posterior branch which goes to the posterior vertebral muscles, and sends a small spinal branch through the corresponding intervertebral foramen to the medulla ...

Bilaterally, the internal thoracic vein arises from the superior epigastric vein, and accompanies the internal thoracic artery along its course. [1] It drains the intercostal veins, although the posterior drainage is often handled by the azygous veins. [1] It terminates in the brachiocephalic vein. [2] It has a width of 2-3 mm. [3]
