I am doing an assignment on anatomy and physiology. Specifically related to the musculoskeletal system. I am going to investigate the structure and function of different bones and a synovial joint in the body. I will show the relationship between the nervous and musculoskeletal systems. I intend to explore one disease of the musculoskeletal system and find out what it is like to live with said disease and found out how much people really know about it.
What is anatomy and physiology?
Anatomy: The study of the different parts of the body and the relationships between them.
Physiology: How each of these parts functions.
Composition of bone
Bones are made up of many different cells and minerals. The three main types of cells are

They are responsible for making sure old bone goes out and new bone is laid down. They are also used to transmit signals through the body through canaliculi's.
Osteoclasts: These are actively involved in the process of bone reabsorption (and therefore the process of forming new bones). Reabsorption and formation of bone becomes less smooth and uniform the older you get. More osteoclasts can form than osteoblasts, in this case osteoporosis can manifest itself.
Bone is also made up of a lot of collagen which is the most abundant protein in the body. There is cancellous bone (spongy, internal bone) and compact bone (harder and external bone). At the joints between bones there is hyaline cartilage that acts as a shock absorber and allows the bones to glide along each other. Inside bones there is a substance called bone marrow. Red bone marrow is present when you are younger and many blood cells are formed here . This red bone marrow then turns into fatty non living yellow bone marrow over time. Bone is made up of many layers and tiny substances as well. Which all work together in ensuring that our skeletons protect and support us while still allowing us to move freely and
