Intercostal arteries

The video tutorial explains the intercostal arteries, focusing on their origin, course, and anastomosis. It covers the posterior intercostal arteries arising from the aorta and the anterior intercostal arteries from the internal thoracic artery. The tutorial highlights the anastomotic connections between these arteries, providing collateral circulation. The anatomical orientation and visual aids help in understanding the arterial supply to the thoracic wall.
