At the ends of long bones in synovial joints
Verified step by step guidance

Step 1: Understand the structure and function of hyaline cartilage. Hyaline cartilage is a type of connective tissue that provides smooth surfaces for joint movement, reduces friction, and absorbs shock. It is characterized by its glassy appearance and is composed of chondrocytes embedded in a matrix of collagen fibers and proteoglycans.
Step 2: Identify the locations of hyaline cartilage in the body. Hyaline cartilage is found in specific areas, including the ends of long bones in synovial joints, the nose, the trachea, and the larynx. It is not present in the external ear, dermis of the skin, or intervertebral discs.
Step 3: Compare hyaline cartilage with other types of cartilage. For example, elastic cartilage is found in the external ear and epiglottis, while fibrocartilage is found in intervertebral discs and the menisci of the knee. This helps clarify why hyaline cartilage is not located in these areas.
Step 4: Relate the function of hyaline cartilage to its location at the ends of long bones in synovial joints. Its smooth surface and ability to withstand compressive forces make it ideal for facilitating movement and reducing wear and tear in joints.
Step 5: Confirm the correct answer based on anatomical knowledge. Hyaline cartilage is specifically located at the ends of long bones in synovial joints, which aligns with the correct answer provided in the problem.
