Bone tissue also known as osseous tissue serves to protect and support. According to Elaine Marieb and Katja Hoehn’s book (2016) bones have seven important functions which are: support for organs; protection for the brain, spinal cord, and vital organs; movement of the body; mineral and growth storage such as calcium and phosphate; body cell formation such as blood cell formation (hematopoiesis); triglyceride (fat) storage which is then used as an energy source; and hormone production such as osteocalcin. There are different shapes of bones like long bones, short bones, flat bones, and irregular bones. Long bones are bones that are longer in length than in width while short bones are bones that are shaped somewhat like a cube. Flat bones are bones that are flat and thin while irregular bones are differently shaped bones with no specific shape. All the bones in the human skeleton are also separated by location. The axial skeleton consists of the rib cage, vertebral column, and the skull which in all, forms the long axis of the body. The appendicular on the other hand, consists of the limbs, pectoral girdle, and pelvic girdle. The bone also consists of two layers, which are the compact bone and spongy bone. Compact bone is the outer layer which is smooth and solid while the spongy bone, the inner layer has the appearance of a “honeycomb”.
Furthermore, there are five major cell types of bone tissue. Those five cell types are osteogenic cells, osteoblasts, osteocytes,…
