There are three forms of cartilage found in the human body; hyaline cartilage, fibrocartilage and elastic cartilage[1]. Cartilage consists of chondroblasts cells and chondrocytes cells within a matrix which they secrete[2]. Chondroblast cells mature into chondrocytes

Contents

Hyaline Cartilage

Hyaline cartilage has a glassy appearance and is found in the ribs, nose and trachea[3]. Hyaline cartilage matrix mainly contains collagen type ll and aggrecan which add strength to the cartilage[4][5].

Fibrocartilage

Fibrocartilage is opaque white in appearance[6]. It consists of layers of alternating hyaline cartilage and collagen fibres[7]. Fibrocartilage is found in invertebral disks and ligamnets[8].

Elastic Cartilage

Elastic cartilage is yellow in appearance and is found in the external ear, larynx and epiglottis[9]. Elastic cartilage occurs in sites that have vibrational functions, such as laryngeal sound wave production and collection of sound waves in the ear[10].
