Deffense [45]

Answer:

The correct answer will be- to provide smooth surface at the ends of synovial joint.

Explanation:

Articular cartilage is the white smooth tissue present at the end of the bones which covers the bones at the joints. The articular cartilage is devoid of the nerves, blood vessels and lymphatics but is exposed to the biochemical environment.

The cartilage at the joint helps in the movement of the bones by reducing the friction produced by gliding or sliding of the bones over each other.

Thus, to provide a smooth surface at the ends of synovial joint is the correct answer.
