The Orign of Bones

Cartilage in this area is rare and contains only minimal mechanical factors, so a fracture is formed in the cranial sac. By inspecting rats at different intervals during the repair period, Girigs & Pritchard (1958) was able to support the study of Pritchard (1948). They discovered that due to low oxygen demand of cartilage, they act as a temporary bridge between fracture gaps until the blood supply recovers. Autoradiographic studies of cellular responses in fracture repair were performed using thiopurine in 5 week old female rats at 42 weeks of age.

There are four main types of bones. They are long bones, short bones, flat bones and irregular bones. The main differences in bones are their shape and their material. As with each type of graph, the four types of graphs are described in detail below, showing the main differences. The main feature of distinguishing long bones from other types of bones is that long bones grow much longer than them. This axis is called the backbone. Longbone is composed mainly of dense bone, bone marrow and cancellous bone are fewer than other kinds of bone. Most of the upper and lower limb bones are classified as long bones, except for the wrist, ankle, and knee bones.

As the name suggests, long bones are much longer than their width. The long bone has a shaft and two ends that are normally inflated. All the limbs except the tibia (knee bone) and carpal tunica and tibia are long bones. The names of these bones are elongated and not the overall size. Three bones of each finger are long bones, even if they are small. Short bones are approximately in the shape of a cube. An example of a wrist and ankle bone. Sesamoid bone is a special type of short bone forming a tendon (humerus etc.). Sizes and numbers vary from person to person. Some bone-like bones may change the tension direction of the tendons. The function of others is not clear

As its name suggests, bones are small round bones shaped like sesame. These bones are formed in tendons (the sheath of the tissue connecting the bones and the muscles) and exert a large pressure on the joints. Bones protect tendons by helping to overcome stress. The number and location of Sesamoid bones are different for different people, but are usually found in tendons related to the foot, hands, and knees. The humerus (single = tibia) is the only bone that we can find. Table 6.1 summarizes bone classification and related features, functions and examples.
