Which connective tissue acts as a cushion between joints and allows for flexibility?

Cartilage is the connective tissue that acts as a cushion between joints and allows for flexibility. Its unique composition, which includes a gel-like ground substance and specialized cells called chondrocytes, provides both strength and the ability to withstand compressive forces. This cushioning is particularly important in joints, as it helps to absorb shock and reduce friction between the bones during movement. Additionally, cartilage is semi-rigid, allowing for flexibility, which is essential in areas such as the nose, ears, and joints.

The other types of connective tissues have different structures and functions. Bone is hard and provides support and structure, but it is not flexible and does not cushion joints like cartilage. Loose connective tissue serves to hold organs in place and provide some cushioning, but it does not provide the same level of support and flexibility in joints as cartilage. Fibrous connective tissue, known for its tensile strength, forms tendons and ligaments, connecting muscles to bones and bones to other bones, respectively; however, it lacks the compressive cushioning properties of cartilage.
