Firm, rubbery matrix is a structural feature of which connective tissue type?

Connective tissues are the tissues that are responsible to connect, support, bind, or to separate out other tissues or organs, that have relatively few cells embedded in an amorphous matrix, often with collagen or other fibers, that includes cartilaginous, fatty, and elastic tissues. Cartilaginous tissues are responsible for the firm, rubbery matrix that provides flexibility. These tissues give shape to the external ear, the larynx (voice box) which is the most easily palpated cartilages in the body, and to the tip of the nose.
