A variation can mean something that is slightly different from similar items of its type (also a variant or variety). It can also apply to a difference itself (e.g. a variat â¦ ion in temperature). In mathematics, variation is the function that compares values among variables.
Cartilage is a type of elastic connective tissue which acts as rubber-like padding to cover and protect the ends of bones at joints. It is a dense matrix of elastic and collagen fibers which are embedded in rubber like ground substance.
Cartilage /ËkÉrtÉ¨lÉ¨dÊ/ is a flexible connective tissue in animals, including the joints between bones, the rib cage, the ear, the nose, the bronchial tubes and the intervertebral discs. It is not as hard and rigid as bone, but it is stiffer and less flexible than muscle.artilage is classified in three types, elastic cartilage, hyaline cartilage and fibrocartilage, which differ in relative amounts of cartilage. Chondroblasts that get caught in the matrix are called chondrocytes. Cartilage does not contain blood vessels (avascular) or nerves (aneural).
