Name the tissue Taf smoothens bone surface at joints describe structure with help of a diagram?

The tissue that smoothens bone surfaces at joints is called articular cartilage. It is a type of hyaline cartilage, which is a smooth, flexible, and shock-absorbing tissue. Articular cartilage covers the ends of bones at joints, where it helps to reduce friction and wear and tear.

Articular cartilage is composed of specialized cells called chondrocytes, which are embedded in a matrix of collagen fibers and proteoglycans. Chondrocytes produce the matrix, which is responsible for the tissue's strength and resilience. Articular cartilage is avascular, meaning that it does not contain any blood vessels. This means that it receives its nutrients from the synovial fluid that surrounds it.

The structure of articular cartilage can be seen in the following diagram:

The diagram shows the different layers of articular cartilage, including the superficial layer, the middle layer, and the deep layer. The superficial layer is the thinnest layer and is composed of small, densely packed chondrocytes. The middle layer is the thickest layer and is composed of larger, less densely packed chondrocytes. The deep layer is the deepest layer and is composed of large, flattened chondrocytes.

Articular cartilage is a very important tissue that plays a vital role in the function of joints. It helps to reduce friction and wear and tear, and it also provides a smooth, gliding surface for bones to move against each other.
