Lower Extremity• Anthropologists can tell the difference
between a male and a female by the shape of the pelvic bones and cavity, and the subpubic angle. (1)

Ribs and Sternum
True ribs (1-7) - attach to the sternum by costal cartilages. The hyaline cartilage makes the breathing process easier. (1.)
False ribs (1-5) – attach to the costal cartilage , not directly to the sternum Instead, the cartilages of the upper three false ribs join the cartilages attached to the ribs above (1.)
Floating ribs(1-2) – have no attachment with the sternum. (1.)
• Total of 7 true ribs on each side, making it 14 true ribs total
• Total of 5 false ribs on each side, making it 10 total false ribs
• Out of the false ribs there are 2 floating ribs on each side, making it a total of 4
The sternum is located in the center of anterior thoracic wall, consist of three segments these segments fuse to form a long flat bone , and also covers and protects the heart. (1.)
Manubrium - Triangular-shaped ,superior portion of sternum. (1.)
Ziphoid Process
Body - middle segment of sternum , long flat narrow plate that forms the center of the front of chest (1.)
