MICROANATOMY

Detailed explanation-1: -There are three types of cartilage: hyaline, fibrous, and elastic cartilage. Hyaline cartilage is the most widespread type and resembles glass. In the embryo, bone begins as hyaline cartilage and later ossifies. Fibrous cartilage has many collagen fibers and is found in the intervertebral discs and pubic symphysis.

Detailed explanation-2: -The larynx has hyaline cartilage, nose and ear have yellow elastic cartilage. Therefore the only part of the body from the above options which does not have cartilage is the kidney.

Detailed explanation-3: -The primary cell that makes cartilage is the chondrocyte, which resides within the lacunae. The matrix of cartilage consists of fibrous tissue and various combinations of proteoglycans and glycosaminoglycans.

Detailed explanation-4: -Hyaline-most common, found in the ribs, nose, larynx, trachea. Is a precursor of bone. Fibro-is found in invertebral discs, joint capsules, ligaments. Elastic-is found in the external ear, epiglottis and larynx.
