What is the primary function of the meniscus in the knee joint?

The primary function of the meniscus in the knee joint is to act as a cushion and stabilize the joint. The meniscus is a C-shaped cartilage structure located between the femur (thigh bone) and the tibia (shin bone). It plays a crucial role in load distribution, reducing the impact on the joint during activities such as walking, running, and jumping. By absorbing shock, the meniscus helps to protect the articular cartilage, which covers the ends of the bones in the joint, thereby preventing wear and tear.

Additionally, the meniscus assists in stabilizing the knee joint during movement. It helps to maintain proper alignment of the femur and tibia, which is essential for joint stability and function. The meniscus also contributes to the overall congruity of the joint, ensuring that the surfaces interact smoothly, reducing the risk of injury and degeneration over time.

The other options relate to functions that are either not primarily associated with the meniscus or pertain to other structures in the body. For example, increasing mobility is more related to the ligaments and muscles surrounding the joint. Supporting blood circulation is a function of the vascular system, while facilitating nerve connections is pertinent to the nervous system and does not specifically describe the role of the
