• What are the two major parts of skeleton?

  1. Axial Skeleton
  2. Appendicular Skeleton
• It is one of the major part of the skeleton which forms the axis of the body. It includes the skull, vertebral column (spine) and rib cage. Its bones, along with ligaments and muscles, allow the human body to maintain its upright posture. It also transmits weight from the head, trunk, and upper extremities down the back to the lower extremities.

  Axial Skeleton
• It is one of the major part of skeleton which forms the appendages and their attachments to the axial skeleton. It includes the bones of the arms and legs, heads and feet, and shoulder and pelvic girdles. Its bones make possible locomotion and other movements of the appendages. They also protect the major organs of digestion, excretion, and reproduction.

  Appendicular Skeleton
• It is an organ made of dense connective tissues, mainly the tough protein collagen. It contain blood vessels, nerves, and other tissues. It is hard and rigid due to deposits of calcium and other mineral salts within their living tissue.

  Bone
• It is an organ system that provides an internal framework for the human body.

  Skeletal System
• It is a type of dense connective tissue, made up of tough protein fibers. It is strong but flexible and very smooth. It covers the ends of bones at joints, providing a smooth surface for bones to move over.

  Cartilage
• These are bands of fibrous connective tissue that holds bones together. They keep the bones of the skeleton in place.

  Ligaments
• It is a fibrous connective tissue that attaches muscle to bone. It serves to move the bone or structure.
