Red Bone Research Paper

A bone is made up of different tissues that work together: bone, cartilage, dense connective tissue, epithelium, various blood forming tissues, adipose tissue and nerve tissue(coursehero). All individual bones are organs. Bones along with their cartilages make up the skeletal system. Bone makes up eighteen percent of the weight of a human body. There are two hundred six bones in the in the adult skeleton, more than half are found in both the hands and feet. The functions of a bone are support, protection, attachment site for muscles making movement possible, storage of the minerals, calcium and phosphate or mineral homeostasis, blood cell production occurs in red bone marrow called hematopoiesis, and energy storage in yellow bone marrow. …show more content…

The activity of the epiphyseal plate can increase in length with the diaphysis. When the epiphyseal plate closes, it is replaced by bone. The epiphyseal line appears and indicates that the bone has completed its growth in length. Cartilage cells are produced by mitosis and are destroyed and also replaced by bone on diaphyseal side of the plate. Zone of calcified cartilage contains mostly dead chondrocytes invaded by osteoclasts and osteoblasts, zone of resting cartilage firmly joins the epiphyseal plate to the epiphysis, zone of proliferating cartilage is where chondrocytes divide to replace those at the diaphyseal side of the epiphyseal plate and zone of hypertrophic cartilage is large maturing
