ON THIS PAGE: You will find a basic drawing of the skeleton, which is the part of the body affected by this disease, as well as a close-up view of the inside of a bone. To see other pages, use the menu.
The image is a drawing of a full adult skeleton. The adult human skeleton consists of 206 bones. A cross section of the femur (thigh bone) shows 3 different parts of a human bone. It shows cartilage as a thin layer at the head of the femur where it connects to the pelvis. The hard outer surface of the bone (called compact bone) surrounds a spongy red tissue called marrow.
