THE HUMAN BODY. 



The two hip-bones come together in front. Behind 

 they are separated by the sacrum. The cavity inclosed 

 between them is the pelvis, or basin. 



3, The femur, or thigh-bone, is the 

 longest bone in the body. 

 It has a round head, which 

 fits into a socket in the hip- 

 bone. At its lower end it 

 spreads cut to make a broad 

 surface for the knee-joint. 

 It is slightly curved.

4. In front of the knee is 

 a small bone, heart-shaped, 

 which is called the patella, 

 or knee-pan. 



5. The leg has two bones, 



the tibia (Latin, tibia, a flute) and the fibula (Latin, fibula, 

 a shawl-pin). The tibia is a strong bone. It has a sharp 

 ridge in front, which is called the shin. The tibia is 

 joined to the femur above. The fibula is a long, slender 

 bone. It is joined to the tibia above and below. The 

 lower ends of these two bones are joined to the ankle-
