The intercostal spaces are filled by the three groups of intercostal muscles.
Each of these spaces contains several layers of intercostal muscles each of which has a different specific function. Every space consists of intercostal muscles and neurovascular bundle of intercostal plane. The intercostal space fig. Interpleural space mediastinum.
Moreover they are traversed by the nerves arteries and veins of the thoracic cage such as intercostal arteries and veins. Since there are 12 ribs on each side there are 11 intercostal spaces each numbered for the rib superior to it. 3 3 contains the external intercostal the internal intercostal and the innermost intercostal muscles arranged in three layers. Called also proximal or proximate space.
