The term 'muscle-bone connection' refers to the relationship between muscles and bones in the body. This connection is made up of two components: SINEW (5 letters) and TENDON (6 letters). SINEW is a type of connective tissue that attaches muscle to bone, while tendons are fibrous cords of tissue that attach muscles to bones. Together, sinews and tendons form the muscle-bone connection, allowing for movement and stability in the body.
