Answers
Answer:
Joints are the areas where 2 or more bones meet. Most joints are mobile, allowing the bones to move. Joints consist of the following:
Cartilage. This is a type of tissue that covers the surface of a bone at a joint. Cartilage helps reduce the friction of movement within a joint.
Synovial membrane. A tissue called the synovial membrane lines the joint and seals it into a joint capsule. The synovial membrane secretes a clear, sticky fluid (synovial fluid) around the joint to lubricate it.
Ligaments. 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. 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.
Bursas. 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.
Meniscus. This is a curved part of cartilage in the knees and other joints.
