Question 2: (How often do you catch a cold?)
you said 2 right?
Answer:
Provide a smooth surface at the ends of synovial joints
Explanation:
Cartilage is the smooth elastic tissue that covers and protects the ends of the long bones. This structural component is present in nose and ear. Different types of cartilage are hyaline cartilage, articular cartilage and so on.
Articular cartilage may be defined as a type of hyaline cartilage that are present on the articular surfaces of the long bones. Articular cartilage is present in close association of menisci. This cartilage provides the smooth surface to the synovial joints and bathed in the synovial fluid.
If I had to pick one I would say that it would be because it can extend a joint beyond its regular range of motion.
