The cartilage type that lines the end of long bones in synovial joints is:
Correct Answer: C
Rationale: The correct answer is C: Hyaline cartilage. This type of cartilage is found at the ends of long bones in synovial joints because it provides a smooth surface for articulation, reducing friction and allowing for smooth movement. Hyaline cartilage is the most common type of cartilage in the body and is characterized by its glassy appearance and ability to withstand compressive forces. Fibrocartilage (choice A) is found in intervertebral discs and has more collagen fibers, making it tougher but less flexible than hyaline cartilage. Elastic cartilage (choice B) contains more elastic fibers and is found in structures like the external ear and epiglottis, providing flexibility and resilience. Cellular cartilage (choice D) is not a recognized type of cartilage and is an incorrect choice.
