What is the sort of substance that cushions ends bones and form flexible parts like ear nose?

The substance that cushions the ends of bones and forms flexible parts like the ears and nose is called cartilage. Cartilage is a type of connective tissue that is found in many parts of the body, including the joints, ears, nose, trachea, and rib cage. It is made up of specialized cells called chondrocytes, which are embedded in a matrix of collagen and other proteins. Cartilage is strong and flexible, and it helps to protect bones and other structures from damage. It also plays a role in shock absorption and joint lubrication.
