Los Angeles, CA (prHWY.com) June 28, 2012 - The human body has many interesting skeletal system facts that will surprise you. It is a well-known fact that the human body consists of 206 bones, but did you know that a baby is actually born with 350 bones? By the time a human reaches adulthood, about 90 bones fuse to form the adult bone structure. This is just one of many surprising skeletal system facts.

Different types of bones
The human body has an eclectic mix of bones. While the skull and sternum are made of flat bones, the hip and spinal cord have irregular bones. The femur or thigh bone is the longest bone in the human body, while the ankle and wrist bones (sesamoid) are the shortest.

The bone structure
The bone tissue is made up of mineralized osseous tissues. The reason why bones are rigid and have a three-dimensional structure is because of this tissue. Blood vessels, nerves, cartilage, marrow, endosteum and periosteum are all part of the bone structure. Calcium and phosphorus are inorganic salts that form a network of bone cells inside the bone tissue.

Bone cells and their importance
Since bones are hard and brittle many people believe that they are made up of dead cells. But the fact is that bone cells have their own network of blood vessels and nerves and are very much alive. The calcium stored in the bones make them hard and also helps in the everyday wear and tear of the human body. Even if there is a fracture, the living cells in the bones can repair and heal the bone.

Storage of nutrients
The bones in the human body play a vital role in storing nutrients and proteins. The bone marrow also stores fatty acids and absorbs alkaline salts. This is important because it keeps the skeletal system healthy and contributes to the overall well being of the body. Bones also help maintain the pH balance of the blood.

Other interesting facts
* The smallest bone in the human body is in the ear, which is size of a rice grain and is called the 'stirrup'
* The human face has 14 bones, while the hand has 27 bones
* The number of bones in a human neck and a giraffe are the same

Keeping the skeletal system and bone structure healthy, by following proper diet with plenty of calcium, is vital for overall good health.
