A Guide to the Human Skeletal System
This is the right place to learn about the bones of the body and their importance. The bones of the body are well explained in this article.
The skeletal system is the structure that gives the mechanical body support. All parts of the body get support from the skeletal system. Motion of the body is facilitated by the skeletal system.
The skeletal system consists of over 200 bones, cartilage, and ligaments. The skeletal system is made up of bones, ligaments, and cartilage.
The model of a skeleton structure shows the bones and the teeth; however, ligaments and cartilage are also there but not so visible. 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.
For the proper functioning of the joints, the ligaments must be there. The bands of dense and fibrous connective tissues are what we refer to as the ligaments. On the other hand cartilage is responsible for the structure of the larynx and the nose. The bones are less flexible than the cartilage.
The bones give the body the structure and enables movement. The face gets the structure from the skull; the skull also protects the brain. Over 30 bones consists the spine. The three limbs that consist the skeletal system includes the upper and lower limbs as well as the girdles. The four limbs are attached to the vertebral column by the girdle.
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 vertebral column is responsible for the structure and the protection of the spinal cord.
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 appendicular skeleton is responsible for the movement while the bones of the axial skeleton give protection to the inner organs.
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.
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.
