ANSWER:

Your musculoskeletal system includes bones, muscles, tendons, ligaments and soft tissues. They work together to support your body's weight and help you move. Injuries, disease and aging can cause pain, stiffness and other problems with movement and function

Your MUSCLE fibers contract (tense up) in response to the message. When the muscle activates or bunches up, it pulls on the tender.

Your BONES work with muscles and joints to hold our body together and support freedom of movement

TENDERING usually refers to the process whereby governments and financial institutions invite bids for large projects that must be submitted within a finite deadline.

LIGAMENT often connect two bones together, particularly in the joints: Like strong, firmly attached straps or ropes, they stabilize the joint or hold the ends of two bones together.
