Bursae are flattened fibrous sacs wedged between adjacent structures, while tendon sheaths are elongated fibrous sacs that wrap around tendons. As forces acting on a joint increase, the body will automatically increase the overall strength of contraction of the muscles crossing that joint, thus allowing the muscle and its tendon to serve as a dynamic ligament to resist forces and support the joint.
