Detailed explanation-1: -In the majority of vertebrate species the sclera contains cartilage and in some cases also bone, which give an extra degree of support to the eyeball (Caprette et al., 2004; Franz-Odendaal and Vickaryous, 2006). Commonly this is a hyaline cartilage layer forming a cuplike structure within the sclera.

Detailed explanation-2: -Cartilage is a soft connective tissue found in nose, ear and larynx. It provide flexibility and support and also protect the organs. Cartilage is not found in kidney.

Detailed explanation-3: -The eye sits in a protective bony socket called the orbit. Six extraocular muscles in the orbit are attached to the eye. These muscles move the eye up and down, side to side, and rotate the eye. The extraocular muscles are attached to the white part of the eye called the sclera.

Detailed explanation-4: -Where is cartilage located? Almost any place where two bones meet in your body is cushioned by cartilage. It’s also at the ends of all your bones that form joints.
