Cartilage is a type of dense connective tissue. It is composed of specialized cells called chondrocytes that produce a large amount of extracellular matrix composed of collagen fibers, abundant ground substance rich in proteoglycan, and elastin fibers.  Cartilage is used as protection in between bones and discs in the spinal cord.  It is very pliable and perfect for insulation.  Cartilage’s absence can be quite painful, as bone on bone contact causes a great deal of discomfort.

Bones are rigid organs that form part of the endoskeleton of vertebrates. They function to move, support, and protect the various organs of the body, produce red and white blood cells and store minerals.  Bones have a thick and strong exterior and a soft interior.  There are about 206 of them in the body, with the most (26) being found in the hand, alone.

Bones are the individual components of the basic body framework called skeleton in humans and other animals with back bones. The bones are hard and rigid. The rigidity and strength of bones enable it to provide the skeleton its shape. It also gives it strength to bear the body weight and withstand stresses and strains to which body is exposed during various activities carried out body and its limbs. Bones also protect the internal organs in the body.

Cartilages are semi-rigid part found in the body of animals with backbone. In terms of their rigidity and strength, cartilage lie between bones and soft tissues like muscles. Cartilage are present in joints between long bones and vertebra of spine. Here the cartilage serve the function of absorbing shocks to which bones are subjected and to prevent bones fro rubbing against each other. Some other part of bodies such as ear and respiratory passage to give them their specific shape combined with flexibility.

Young ones of animals with backbones have their skeleton made of cartilage instead of bones. This gets converted in bones before birth.
