Y1 - 2019 N1 - T2 - Joint Structure & Function: A Comprehensive Analysis, 6e AB - Thorax is a term that is used to describe the bones of the rib cage, the fascia and muscles that attach to the rib cage, the visceral organs within the rib cage, and even the skin that covers the rib cage. The rib cage, also called the thoracic cage or the bony thorax, consists of the thoracic vertebrae, the ribs, and the sternum (Fig. 5–1). The rib cage provides a foundation for many of the muscle attachments of the upper extremities, head and vertebral column, and pelvis. The rib cage also provides protection for the heart, lungs, and viscera. Therefore, there needs to be a certain amount of inherent stability to the thorax. The structure of the rib cage significantly increases the stability of the thoracic spine during flexion/extension, lateral bending, and rotation.1,2 One of the important functions of the chest wall is its role in ventilation. The process of ventilation, including inhalation/exhalation(inspiration/expiration), depends on the mobility of the rib cage and the ability of the muscles of ventilation to move it.3 SN - PB - F. A.
