    I am going to describe bone formation and growth in this lecture. As I pointed out in another lecture in this histology course, there are number of very important functions of bone does and I will repeat them here because when we talk about bone growth and bone formation, the idea is to create bone in the adult can support these different functions such as protecting the heart, lungs and brain, vital organs, forming the skeleton and allowing us to move, supporting the body and body weight. It's also a mineral reserve and I will explain that towards the end of this lecture. It's a reservoir for calcium and phosphate. And I have also given a lecture on bone marrow in this lecture series, in this histology course and there I described the importance of bone marrow and how it is housed within spongy bone and also the medullary components of young bones. At the end of this lecture, I would like you to be able to understand the processes of firstly bone formation, but then the difference between intramembranous ossification and endochondral ossification. I will briefly describe how bone is mineralized to become a very hard structure and then also describe the structure of a synovial joint. So it is important that you understand each of these topics that I have listed on the left-hand side here. On the right hand side, you can see the head of the femur that is going to articulate with the hip bone. And I am going to describe just as an introduction to this lecture, some of the major components of a long bone, of a bone that makes up an axial skeleton, a bone that makes us move by the action of skeletal muscles on it. There are different sorts of...
