To discuss:
Number of ribs; true, false, and floating ribs.
Introduction:
The thoracic cage consists of three major parts namely thoracic vertebrate, sternum, and ribs. It protects the lungs and hearts by forming a rough conical enclosure, and it also produces attachment for the upper limb and pectoral girdle. It contains the broad base and the narrower superior apex. The inferior border of the thoracic cage is known as costal margin (arc of the lower ribs). Other than thoracic organ, it protects the liver, spleen, and kidneys. The main role of the thoracic cage is regulation of breath.
