Bone joint and muscles

The bone joint and muscles in the human skeleton system responsible for growth and for movement. So we discuss separately bone joint and muscles.

What are bones?

The human skeleton consists of 206 bones in the body. Our bones start to develop before birth. When the human skeleton first forms, it is made of flexible cartilage, but within a few weeks, it begins the process of ossification. Ossification is processed when the cartilage is replaced by hard deposits of calcium phosphate and stretchy collagen, the two main components of bone. This process takes 20 years for completing bone structure strong.

Bones are made of calcium, phosphorus, sodium, and other minerals, as well as the protein collagen. Calcium needed to make bones strong, hard, which allows them to support your weight. Bones contain calcium and release some into the bloodstream when it is needed by other parts of the body. The amounts of vitamins and minerals that you eat in your diet, especially vitamin D and calcium, directly affect how much calcium is stored in the bones.

The soft bone marrow inside our bone structure is where most of the blood cells flowing through our bodies are made. The bone marrow consist of stem cells, which produce the body’s red blood cells and platelets, and some types of white blood cells. Red blood cells associated with carrying oxygen to the body’s tissues and platelets help with blood clotting when someone has a cut or wound. White blood cells help the body against fight infection.

There is two types of bone material in the human body— compact bone and cancellous bone. Compact bone is a type of bones contain the solid, hard outside part of the bone. Compact bone makes up most of the human skeleton. It looks like ivory and very strong. It runs by carrying blood vessels and nerves from the periosteum in the Holes and channels. Cancellous bone is a type of bone structure which looks like a sponge, is inside the compact bone. It is of a mesh-like network of tiny pieces of bone called trabeculae.

What are the muscles?

Bones unable to work alone, they need help from the muscles and joints. Working mechanisms of Muscles by pulling on the joints, allowing us to move. They help the body perform other functions so we can grow and remain strong, such as chewing food and then moving it through the digestive system.

The human body made of more than 600 muscles. Muscles make the weight in the body because it contains nutrient elements. Muscles with the help of bones make tough, cord-like tissues called tendons, which allow the muscles to pull on bones. If you move your fingers, you able to see the tendons on the back of your hand move as they do their work.
