Each rib is a curved, flattened bone that contributes to the wall of the thorax. Consider the force of an electromagnetic wave on the electrons in an antenna. The diaphragm is the primary muscle that is active in inspiration. 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. In the earlier lessons was found that for typical values of the current the drift velocity is about 0.01m/s0.01 \mathrm{~m} / \mathrm{s}0.01m/s. The thoracic cage is formed by the 12 pairs of ribs with their costal cartilages and the sternum. While every effort has been made to follow citation style rules, there may be some discrepancies.

When assessing a patients level of alertness sometimes a sternal rub is performed with the knuckles to see if they respond to pain. They articulate with the vertebral column posteriorly, and terminate anteriorly as cartilage (known as costal cartilage). - Bifid spinous process - this is where the spinous process splits into two distally The Lymphatic and Immune System, Chapter 26. Rib 10 only has one facet for articulation with its numerically corresponding vertebra. If two or more fractures occur in two or more adjacent ribs, the affected area is no longer under control of the thoracic muscles. "All the pressures, the traffic . The rib cage is collectively made up of long, curved individual bones with joint-connections to the spinal vertebrae. The configuration of the lower five ribs gives freedom for the expansion of the lower part of the rib cage and for the movements of the diaphragm, which has an extensive origin from the rib cage and the vertebral column. Flail chest is treated by fixing the affected ribs, preventing their paradoxical movement. - The false ribs (8-12) either attach to the sternum indirectly or not at all.
