As stated in the previous paper, the skeletal system is responsible for many functions that insure a healthy human body. For example, bones are responsible for support, movement, protection of vital organs, the production of red blood cells, and also maintaining mineral concentrations in the compact bone (Clarke). There are different types of bones throughout the body, all responsible for specific functions and have differing compositions. All bones contain osteoclasts, which are responsible for breaking down bone, and osteoblasts, which replace the lost bone, that are negatively correlated with each other during the process of bone growth. This paper will focus on long bones, what happens within the bone when it experiences a break, and the …show more content…
It can be divided into gap healing and contact healing. Gap healing is initialized by woven bone filling the fissure, with no connective tissue or fibrocartilage. Next, the remolding stage occurs, where osteon substitutes the new bone and the fractures ends. Contact healing, on the other hand, happens when there is direct contact between the two fractures ends and osteons can grow through the area. What happens during this process is that osteoblasts on one end undergo reabsorption and create cutting cones across the break. This process promotes a cavity, which aids in the formation of blood vessels that work endothelial cells and osteoprogenitor cells that help form osteon from osteoblasts (Lieberman & …show more content…
The therapy entailing the release of human’s own stem cells into the blood has been determined a new way to help the body repair itself and was founded by a group of British scientists. It has already been known that bone marrow releases stem cells when the body is injured that creates fresh blood to help patients suffering from blood cancer. Sarah Rankin of Imperial College has discovered a way to get marrow to release another kind of stem cell aimed to repair bones, as well as blood vessels and cartilage. Her research done on mice, include a drug called mozobil, included with a natural growth factor, can increase the amount of the stem cell in blood by a hundred. This technique can be a way to speed up sever bone breaks

Types Of Articulations

contact between bones, between a bone and cartilage, or between a bone and a tooth. Synovial joints are the most common type of articulation and feature a small gap between the bones. This gap allows a free range of motion and space for synovial fluid to lubricate the joint. Fibrous joints exist where bones are very tightly joined and offer little to no movement between the bones. Fibrous joints also hold teeth in their bony sockets. Finally, cartilaginous joints are formed where bone meets cartilage…

Essay on Skeletal System

Introduction to Human Skeletal System: Skeletal system is the system of bones, associated cartilages and joints of human body. Together these structures form the human skeleton. Skeleton can be defined as the hard framework of human body around which the entire body is built. Almost all the hard parts of human body are components of human skeletal system. Joints are very important because they make the hard and rigid skeleton allow different types of movements at different locations. If the skeleton…

The Importance Of Bone

Bone is made up of collagen, calcium phosphate, protein and calcium carbonate. There were combinations between collagen and calcium that give strength and flexibility to the bone. Bone is strong because it consists of calcium and have the ability to withstand a stress from break as there is collagen present in the bone. Spongy bone of the spine is most vulnerable because osteoporosis always affect the entire skeleton. Mineral also is present in the bone in order to give additional strength to the…
