What are Two Functions of Cartilage?

Cartilage performs several vital functions in the body. Two key roles are providing structural support and facilitating smooth movement within joints.

Key Functions of Cartilage

1. Providing Structural Support: Cartilage provides a strong yet flexible framework for various body parts. It gives shape to structures like ears and noses, maintaining their stiffness while allowing for flexibility. ¹ Furthermore, cartilage connects the ribs to the breastbone (sternum), offering crucial support to the rib cage. ¹ It also resists compression forces, enhancing the resilience of bones.

2. Facilitating Smooth Joint Movement: In joints, cartilage's smooth surface minimizes friction between bones, enabling easy and pain-free movement. ² This is crucial for activities like walking, running, and bending. The shock-absorbing properties of cartilage protect the bones from damage during movement. ³
