Learn the Bones in Your Body

If you are keen to learn the skeletal system then you have come to the right place. Well, this article explains what the skeletal system does and what comprises it.

The bones of the body gives the body the mechanical support. The skeletal system supports the body. Motion of the body is facilitated by the skeletal system.

Over 200 bones, cartilage and the ligaments make up the skeletal system. The skeletal system is made up of bones, ligaments, and cartilage.

The bones and the teeth are the most visible in a model of the skeleton structure. If you happen to be keen you will be able to see all the constituent parts of the skeleton model. The ligaments and the cartilage are also very basic parts of the skeleton.

Ligaments are vitally important for the proper functioning of the joints. Ligaments are basically the bands of dense and fibrous connective tissues. The cartilage makes up the structures of the nose and the larynx. A cartilage is a bit more flexible than the bone, but it has more strength than the muscles.

Movement and structure of the body comes from the bones. The face gets the structure from the skull; the skull also protects the brain. The spine consists of over 30 bones. The upper and lower limbs, as well as the girdles, make up the three limbs of the skeleton. The girdle facilitates the attachment of the four limbs to the vertebral column.

The skull is made up of several bones which surround the brain thereby giving it protection. The protection is given to the heart, and the lungs comes from the thoracic cavity which surrounds them. The spinal cord is given both structure and protection by the vertebral column.

You may wonder how the skeleton moves. The muscles are always given the signal to move by the nerves that surround the muscles. The muscles contract when the nervous system sends commands to the skeletal muscles. The movement is created between the joints and the bones when muscles contract.

The two groups of the bones consist of the axial and appendicular skeletons. Movement is facilitated by the appendicular skeleton while internal organs are protected by the axial skeleton.

The axial skeleton is made up of the skull, vertebral column, and thoracic cage while the appendicular skeleton consists of the girdles and the limbs.

The five types are: the long bones like the femur, the flat bones like the frontal bone, the patella or the knee cap is typed as the sesamoid bone and the short bones which includes the bones at hand (carpal) and the bones in the feet ( tarsals).
