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.
Growth of cartilage. Unlike bone, which has a hard matrix, cartilage has a flexible matrix which can accommodate mitosis. It is the ideal tissue to use to rapidly lay down the embryonic skeleton and to provide for new skeletal growth.Cartilage grows in two ways.heir chondrocytes are spherical, and the only fiber type in their matrix is fine collagen fibers. Skeletal hyaline cartilages include. 1  Articular cartilages, which cover the ends of most bones at movable joints. 2  Costal cartilages, which connect the ribs to the sternum (breastbone).
