Types of cartilage include hyaline cartilage, fibrocartilage, and elastic cartilage. Hyaline cartilage is the most abundant of the three types. It is found mainly in the bronchial tubes, larynx, nose, and trachea, in the end of long bones, and in the embryonic skeleton.artilage is avascular. Location. Bones make up the majority of the axial and appendicular skeleton. Cartilage is a much softer, more pliable component that is mostly found in between joints of bones (articular cartilage), along the respiratory tract, and in a few other places where flexibility is needed.
