Learning the Bones of the Body
This is the right place to learn about the bones of the body and their importance. The explanation you get here will give you insight into the bones of the body and their roles in the grand scheme of things.
The skeletal system is the structure that gives the mechanical body support. The structure of the body comes from the skeletal system. The skeletal system also facilitates movement.
The skeletal system consists of over 200 bones, cartilage, and ligaments. The bones, ligaments and the cartilage make up the skeleton structure of the body.
If you happen to look at the model of a skeletal system, you would see the bones and the teeth. If you happen to be keen you will be able to see all the constituent parts of the skeleton model. The other basic parts of the skeleton apart from the bones is the ligaments and the cartilage.
Ligaments are vitally important for the proper functioning of the joints. Ligaments are basically the bands of dense and fibrous connective tissues. On the other hand cartilage is responsible for the structure of the larynx and the nose. A cartilage is a bit more flexible than the bone, but it has more strength than the muscles.
The bones give the body the structure and enables movement. The skull helps to protect the brain and is responsible for the structure of the face. Over 30 bones consists the spine. The upper and lower limbs, as well as the girdles, make up the three limbs of the skeleton. The four limbs are attached to the vertebral column by the girdle.
The skull consists of several bones that surround the brain. The protection is given to the heart, and the lungs comes from the thoracic cavity which surrounds them. On the other hand the vertebral column gives the spinal cord structure as well as the protection.
The bones are attached to the muscles. The muscles are always given the signal to move by the nerves that surround the muscles. When the nervous system sends the commands to the skeletal muscles, the muscles contract. When the muscles contract movement is created at the joints between the bones.
The two groups of the bones consist of the axial and appendicular skeletons. The internal organs are protected by the axial skeleton while movement is facilitated by the appendicular skeleton.
Girdles and the limbs make up the appendicular skeleton while skull, vertebral column, and thoracic cage comprise the axial skeleton bones.
You should also should know that there are five types of bones which include the long and short bones, sesamoid bones, the flat bones, and the patella bones.
