Which of the following is a function of articular cartilage?

Articular cartilage plays a crucial role in joint function primarily by minimizing friction between the articulating surfaces of bones. This specialized cartilage is smooth and resilient, allowing for easy and gliding motion during joint movements. By reducing friction, articular cartilage helps to protect the underlying bone and facilitates a more efficient transfer of forces across the joint. This function not only contributes to smoother motion but also helps in absorbing shock during activities such as walking, running, or jumping, thereby playing an essential role in joint health and function.

The other options do not align with the primary functions of articular cartilage. For instance, it doesn’t directly reduce muscle tension, influence joint stability unfavorably, or increase joint torque. Each of these outcomes relates more closely to the action of muscles, ligaments, or the overall design of the joint rather than to articular cartilage itself.
