Axial skeletonIt has function for protect our vital organ, such as brain, lungs and heartAxial skeleton consists of the skull and bony thorax.*skull, its our bones in head, it has function for protecting our brain and support our face (wedge-pelipis, forehead, chick, jaw, eye nose)* Bony thorax consist of sternum + rib cage and spineRib cage has 12 pairs of bones (7 pairs labeled true these bones are connected to the sternum, while 5 other false sets do not. Three of those connect to non sternum and the two are deemed to be floating, which means they only connect to the spine).The function is to protecting our lung and heart from any damages.Spine has 33 small bones, its start from the bottom of the brain ends at the start of our bum. Spine consists by:Neck bone has a function for support our face and protecting our throat, esophagus and vocal cord. We have 7 bones in neck bone.Dorsal spine has a function for protecting our spinal cord, it produce our blood. We have 12 bones in here.Lumbar bone has a function for protect the vertebral column (keseluruhan tulang belakang), it has 5 bonesSacrum (tulang kelangkang) it is responsible for support our upperbody when we seating or standing. We have 5 bonesBody bone has a function for support the bones around the pelvis. We have 4 bones here. The scientist says that without body bone we cant seat comfortly. 2. Appendicular skeletonIt allows our movement to occur through the joints of our arms and legs. Without it we would be unable to move around. Appendicular consists of our hands, legs and spinal.Hand. In our hand we have the humerus, radius, ulna and metacarpalsLegs. Femur (the hardest and longest bone), patella, tibia (we must keep it safely, because it is so hurt when something hit tibia, because of that the football player always use a shield on their tibia), fibula, metatarsals.Pelvis, its the largest bone in human skeleton. It has function for protecting uterus (an organ of the female reproductive system that is responsible for the development of the embryo and fetus during pregnancy) and bladder-kandung kemih (part of our body where urine is stored until it leaves your body).
