Which tissue is found in the outer ear?

The correct choice is elastic cartilage, which is the primary tissue found in the outer ear, known as the pinna or auricle. Elastic cartilage is distinguished by its high concentration of elastic fibers in addition to collagen, providing both flexibility and strength. This unique combination allows the outer ear to maintain its shape while being able to endure bending and flexing without damage.

Hyaline cartilage, while present in other parts of the body such as the nose and trachea, lacks the elasticity necessary for structures that require flexibility. Fibrous cartilage, characterized by its dense and strong collagen fibers, is designed for support and strength, commonly found in intervertebral discs and pubic symphysis, making it unsuitable for the flexible needs of the outer ear. Bone, on the other hand, is a rigid structure that forms the skeleton and does not provide the required flexibility for the outer ear. Therefore, elastic cartilage is the appropriate tissue type that fulfills the functional requirements of the outer ear.
