Which structures act as shock absorbers at the end of bones?

The structures that act as shock absorbers at the end of bones are articular cartilage and menisci (in certain joints like the knee).
  1. Articular Cartilage: This smooth, flexible cartilage covers the ends of bones at joints, reducing friction and absorbing the impact and pressure that occurs during movement, such as walking or running.

  2. Menisci: These are crescent-shaped pieces of fibrocartilage located in the knee joint, between the femur and tibia. They help absorb shock, stabilize the knee, and improve the fit between the bones, allowing smoother movement.

Both of these structures play essential roles in protecting the bones and joints from damage during everyday activities.
