The Human Body Skeletal System
The human skeleton system is made up of bones and joints in the body. The skeleton system has cartilage, tendons and ligaments which are known as tissues these tissues are what connect to the bones of the skeletal system together. Each bone is a complex living organ that is made up of many cells, protein fibers, and minerals. These bones store many different types of substances like calcium minerals, proteins, which aid in growth and repair of the body. Bones consist of many living cells the blood vessels and nerves which help transport the minerals around bones and the skeleton system aid. The skeleton system doesn’t consider teeth as bones , the teeth are made up of the strongest substance enamel and dentin and not the same as a living bone structure inside the body.
Adults have less bones then baby’s. When we are baby’s we are born with three hundred bones at birth, as we grow as baby’s many small bones grow and join together forming larger bones. At the adult stage, there are two hundred and six bones in the human body.
Function and Necessity of the skeleton system:
The main function of the skeleton system is to support and produce movement in the body. Without the skeleton system the body would just be a big blob of fat.
The skeleton system is essential because it protects all the fragile body tissues and vital internal organs in the body.
- The eyes and brain are protected by our Skull
- All spinal cord, heart, brain, lungs and eyes protected by the Ribs
- The spinal cord is protected by the Vertebral column
The human body moves because the muscles that are attached to the bones, muscles are attached to the bones by the tendons, which are inelastic bands. Our skeleton system is light and very strong with the bones , muscles cannot remain in the right place.
