Which type of cartilage are involved to cover the synovial joint
**Core Concept**
The question is testing the knowledge of the types of cartilage found in the human body, specifically those involved in forming the joint capsule of synovial joints. Synovial joints are characterized by their high degree of mobility and are enveloped by a fibrous joint capsule that contains synovial fluid.
**Why the Correct Answer is Right**
The correct type of cartilage involved in covering the synovial joint is hyaline cartilage. This is because hyaline cartilage is a flexible, white, and avascular (without blood vessels) connective tissue that provides a smooth surface for joint movement. It is also resistant to wear and tear, allowing for the smooth gliding of bones within the joint capsule. The hyaline cartilage covers the articular surfaces of the bones, forming the joint capsule.
**Why Each Wrong Option is Incorrect**
* **Option A:** Fibrocartilage is incorrect because it is a dense, white, and avascular connective tissue that provides tensile strength and support, but it is not typically found in the joint capsule of synovial joints.
* **Option B:** Elastic cartilage is incorrect because it is a flexible, yellowish-white connective tissue that provides flexibility and support, but it is primarily found in the external ear, epiglottis, and laryngeal cartilages.
* **Option D:** (no option provided)
**Clinical Pearl / High-Yield Fact**
It's essential to remember that hyaline cartilage covers the articular surfaces of bones in synovial joints, allowing for smooth movement and reducing friction between bones.
**Correct Answer:** C. Hyaline cartilage.
