What does the term 'intercostal' refer to in the context of anatomy?

The term 'intercostal' specifically refers to the anatomical location between the ribs. In anatomy, this term is often used to describe both the spaces and the muscles that are situated in the intercostal spaces – the areas between the ribs. The intercostal muscles, for example, are crucial in the process of respiration as they assist in the expansion and contraction of the thoracic cavity during breathing. Understanding this terminology is essential, especially in fields related to anatomy and physiology, as it helps in identifying structures associated with respiratory functions and the overall anatomy of the thoracic region.
