What do joints do




















Strong ligaments tough, elastic bands of connective tissue surround the joint to give support and limit the joint's movement. Ligaments connect bones together. Tendons another type of tough connective tissue on each side of a joint attach to muscles that control movement of the joint.

Tendons connect muscles to bones. Fluid-filled sacs, called bursas, between bones, ligaments, or other nearby structures. They help cushion the friction in a joint. Synovial fluid. A clear, sticky fluid secreted by the synovial membrane.

This is a curved part of cartilage in the knees and other joints. Strong ligaments tough, elastic bands of connective tissue surround the joint to give support and limit the joint's movement. Ligaments connect bones together. Tendons another type of tough connective tissue on each side of a joint attach to muscles that control movement of the joint.

Tendons connect muscles to bones. Fluid-filled sacs, called bursas, between bones, ligaments, or other nearby structures. They help cushion the friction in a joint. Other joints may move a little, such as the vertebrae. Pads of cartilage menisci act as cushions between the two bones and help distribute body weight in the joint. Fluid-filled sacs bursae provide cushioning between structures such as the tibia and the tendon attached to the kneecap patellar tendon.

Five ligaments along the sides and the back of the knee reinforce the joint capsule, adding stability. The kneecap patella protects the front of the joint. Merck and Co.
