Answer:
A flexible connective tissue, known as cartilage varies from bones in many ways, its microcomposition is less developed in comparison to the bone and is avascular. It is not supplied with nerves and thus depends upon the process of diffusion to attain nutrients. The three kinds of cartilage are fibrous, hyaline, and elastic.
Of these the most widespread kind is the hyaline cartilage, it looks like glass. It is witnessed in embryos, where the formation of bone takes place as hyaline cartilage, which ossifies later. In adults, it is found on the tips of the ribs, on the articular surfaces of the long bones, the parts of the skull, and the rings of the trachea.
Fibrous cartilage is witnessed in the pubic symphysis and intervertebral discs and exhibits many collagen fibers.
Elastic cartilage is witnessed in the internal support of the external ear and the epiglottis and is yellow, springy, and elastic in characteristics.
