The Skeletal System is made up of fused bones

The Skeletal System is made up of fused bones, completed by cartilage and supported by ligaments, tendons and muscles. The human skeleton has 206 bones, which vary in size and shape. They act to support the body, protect vital organs, guarantee movement, produce blood cells and store some mineral salts, such as calcium and phosphorus. Bones are classified according to their shape into five main types: long, short, flat, irregular and sesamoid. Joints can be classified as: Synarthroses, Amphiarthroses and Diarthroses and can also be classified according to the material found between the bones: Fibrous joints, Cartilaginous joints and Synovial joints. The skeleton can be divided into: axial (skull, vertebrae, ribs, sternum and hyoid bone) and Appendicular (limbs and scapular and pelvic girdles).
