Skeletal body

    The skeleton is split up into two parts: the axial skeleton (in the pink), and the appendicular skeleton (in the blue). The axial skeleton consists of the skull, vertebrae, and the rib cage; and the appendicular skeleton consists of the arms, legs, shoulder blades, collarbones, and the pelvis.
  •     Axial skeleton- The portion of the skeleton that supports and protects the head, neck, and trunk.
  •     Appendicular skeleton- The portion of your skeleton that connects to the axial skeleton and has the limbs attached to it.
        Your whole skeleton together is called your endoskeleton (usually referred to as just "skeleton"). The most important part of the endoskeleton is the vertebral column, usually called the vertebrae or backbone. Depending on whether an animal has vertebrae or not divides two different classifications. Therefore, humans are vertebrates along with rabbits, horses, foxes, and many others.
           The arms are connected to your body by something called the pectoral girdle; and your legs are connected to your body by your pelvic girdle. All of these work together to make a complete endoskeleton and keep your body staying upward.
