Learning the Bones of the 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. 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 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. However, there are other structures that you will see if you pay close attention. The other structures you see are the ligaments and the cartilage.
Ligaments are vitally important for the proper functioning of the joints. 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 body structure comes from the bones; the movement of the body is also enabled by the bones. The face gets the structure from the skull; the skull also protects the brain. Up to the tune of 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 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. 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 movement signal to the muscles is always given by the nerves in the muscles. The muscles contract when the nervous system sends commands to the skeletal muscles. The movement at the joints and the bones is made possible by the contraction of the muscles.
The axial skeleton and the appendicular skeleton makes up the two groups of the bones. 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.
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.
