Joints are places where two or more bones meet. Most joints are mobile, which means they allows the bones to move.
Bones are covered with CARTILAGE, which plays a basic role in keeping joints working properly. It creates a smooth surface that provides friction-free gliding for good movement, shock absorption and transmission of forces between bones.
The synovial membrane is a tissue that covers the joint and encloses it in the joint capsule. The synovialmembrane secretes SYNOVIAL FLUID around the joint to lubricate it.
Tendons are structures made of fibrous tissue that act as a functional bridge between the muscle and the bone. Movement is the tendon’s main function, given that it is in charge of transmitting the energy generated by the muscles to help move the joint.
Ligaments are bands of tough, elastic connective tissue that surround the joint to hold it in place and limit its movements.
Muscles are tissues made up of a complex network of protein fibres. Their main features are contractibility and elasticity.
