What is the primary function of articulate cartilage?

• A. Store minerals
• B. Support body weight
• C. Provide protection during movement
• D. Facilitate bone growth

Answer: (C)

Articular cartilage primarily serves to provide protection during movement. This specialized type of cartilage covers the ends of bones where they articulate with other bones, forming joints. Its smooth, slippery surface allows for ease of movement and reduces friction between the bones during activities such as walking, running, or any joint movement. Moreover, it acts as a cushion, absorbing shock and distributing loads effectively across the joint, which helps prevent injuries and wear over time.

While articular cartilage does play a role in supporting body weight and facilitating some aspects of bone growth, its most critical function is to protect the underlying bone and ensure smooth joint function. This protective role is essential for maintaining joint health and function, especially under the stresses that come with athletic activities.
