Answers (1)
While the pinna of the ear is indeed characterized by elasticity, the reason provided, stating that this elasticity is due to the presence of hyaline cartilage in the pinna, is incorrect. The pinna of the ear is primarily composed of elastic cartilage, not hyaline cartilage. Elastic cartilage is a type of cartilage that contains a high proportion of elastic fibers, which provide the pinna with its characteristic flexibility and elasticity. Hyaline cartilage, on the other hand, is a different type of cartilage found in other parts of the body, such as the joints and the respiratory system. Therefore, the correct answer is option 4 which states that the assertion is true, but the reason is false.
