What is cartilage and where is it typically found?

Cartilage is a flexible connective tissue that is known for its translucency and elastic properties. It plays a crucial role in the development of the skeletal system, particularly in vertebrate embryos where it initially forms the template for bones. As the embryo develops, this cartilage can later ossify, turning into bone.

In adults, cartilage is often found in areas where cushioning, support, and flexibility are necessary. Common locations include the joints, where it helps reduce friction and absorbs shock between bones. It is also present in structures such as the nose, ears, and parts of the ribcage. This unique combination of firmness and resilience allows cartilage to provide structural support while still allowing for a degree of movement, making it distinct from more rigid tissues such as bone.
