Learn the Bones in Your Body
If you are keen to learn the skeletal system then you have come to the right place. 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. All parts of the body get support from the skeletal system. The skeletal system also facilitates movement.
The skeletal system consists of over 200 bones, cartilage, and ligaments. So by learning about the skeletal system you would also learn about the bones.
If you happen to look at the model of a skeletal system, you would see the bones and the teeth. However, there are other structures that you will see if you pay close attention. 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. The connective tissues at the joints are what is known as the ligaments. The larynx and the nose structure are made up of the cartilage. The flexibility of the cartilage is higher than that of the bones.
The bones give the body the structure and enables movement. The brain is protected by the skull; the skull also gives face the structure. Up to the tune of over 30 bones consists the spine. The skeletal system also has three limbs, the upper and the lower limbs, and the girdles. The girdle facilitates the attachment of the four limbs to the vertebral column.
The brain is surrounded by several bones which make up the skull. The heart and the lungs are enshrouded by the thoracic cavity giving them protection. 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 nerves in the muscles give the muscles the signal to move. The contraction of the muscles is always informed by the nervous system. The movement at the joints and the bones is made possible by the contraction of the muscles.
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.
The shape and functions of the bones facilitate the typing of the bones.
