It has take millions of year of development or for the evolution of the bones of the human skeleton. The body has 206 bones having different size and shape. All through the years of evolution man's bones have developed in a highly specialised manner.
The human skeleton allows a wide range of movement since it is strong and flexible. The framework of the body is the skeleton and it has many irregular shapes which for a mankind is not easy to understand.His bones continues to grow till a man is in his early 20s. Hereditary to the amount of growth of the bones.
The movement in the body is impossible without the use if bones and muscles. Both are the strongest part of our body and The role of some of the bones are highly important as they protect the vital organs of the body from injury.
A variety of bones go to make up of the skeleton. Every bone performs its separate job in an efficient manner. Great strength is provided by the shorter bones of the body, especially those in the wrist and the foot.
I will try to explain you some parts of bones but not go in detail as some people says its boring to read more content and i will make language more reliable so that content might be easy for you people to read.
THE SKULL
The skull are held together bu structure which are due to immovable joints and they consists of 22 bones. The spine joins the head underneath and towards the middle of the skull so that the head balances on it.
THE SPINE
The spine is composed of a large number of small bones called vertebrae. These bones can move freely because they can easily fit into each other so they are called spine. Seven bones at the top area are called cervical(neck) vertebrae.
THE INSIDE OF THE BOLE
You know bones are made up of solid, rigid matrix of cells filled with calcium and magnesium salts. Bones are also made of one of the strongest tissue in the body which is unbreakable.
JOINTS
There are total 230 joints in the human body which is interconnected with each other bones. The skeleton maintains the shape and movement of the body with the help of joints. As they are joints they can be breakable and removed from each other with some strong medical machinery.
