A typical human rib cage consists of 24 ribs, the sternum (with xiphoid process), costal cartilages, and the 12 thoracic vertebrae. Together with the skin and associated fascia and muscles, the rib cage makes up the thoracic wall and provides attachments for the muscles of the neck, thorax, upper abdomen, and back.
Usually humans have 24 ribs, or 12 pairs. Men and women have the  same number of ribs.In rare cases some people have an extra pair,  or have a pair less than 12, so either 2 â¦ 2, 24, or 26.They are  always in even numbers unless there is some kind of congenital  defect. Ribs 1 to 7 are true ribs (their cartilages attach  directly to the sternum).he upper seven pairs of ribs are true ribs, for a total of 14 true  ribs. Below them are five pairs of false ribs. There are seven pairs of true ribs for a total of 14. They â¦ are also  known as upper ribs and are attached to the sternum.
