Intercostal VAN topography

The video tutorial explains the topography of intercostal veins, arteries, and nerves within the intercostal space. It begins with an orientation of the thoracic wall, highlighting the skin, hypodermis, ribs, and pleural membranes. The tutorial then delves into the intercostal space, describing the external, internal, and innermost intercostal muscles. It details the arrangement of the intercostal vein, artery, and nerve (VAN) between these muscles and their course along the coastal groove of the ribs. The tutorial provides a comprehensive understanding of the intercostal VAN topography.

Explain the relationship between the intercostal muscles and the intercostal vessels.

How does the right 5th intercostal vein course through the intercostal space?
