Auricle of the ear is made of:
Correct Answer: Elastic cailage
Description: There are three types of cailage: Hyaline cailage has a high propoion of amorphous matrix. Throughout childhood and adolescence, it plays an impoant pa in the growth in length of long bones (epiphyseal plates are composed of hyaline cailage). It has a great resistance to wear and covers the aicular surfaces of nearly all synol joints. Fibrocailage has many collagen fibers embedded in a small amount of matrix and is found in the discs within joints (e.g., the temporomandibular joint, sternoclavicular joint, and knee joint) and on the aicular surfaces of the clavicle and mandible. Fibrocailage, if damaged, repairs itself slowly in a manner similar to fibrous tissue elsewhere. Elastic cailage possesses large numbers of elastic fibers embedded in matrix. It is flexible and is found in the auricle of the ear, the external auditory meatus, the auditory tube, and the epiglottis. Elastic cailage, if damaged, repairs itself with fibrous tissue.
