The shallow costal groove runs along the inferior margin of a rib and carries blood vessels and a nerve. When the diaphragm works with the anterolateral abdominal muscles, diaphragm contraction assists in increasing intra-abdominal pressure. They articulate with the vertebral column posteriorly, and terminate anteriorly as cartilage (known as costal cartilage). Flail chest is treated by fixing the affected ribs, preventing their paradoxical movement. What muscle is the most important muscle for respiration? It has a roughened area on its upper surface, from which the serratus anterior muscle originates. A small bump on the posterior rib surface is the tubercle of the rib, which articulates with the facet located on the transverse process of the same numbered vertebra. It is attached anteriorly to the xiphoid process and costal margin, laterally to the 11th and 12th ribs, and posteriorly to the lumbar vertebrae.The posterior attachment to the vertebrae is by tendinous bands called the medial and lateral arcuate ligaments. The ribs are a set of twelve paired bones which form the protective 'cage' of the thorax.
