Which of the following describes how muscles and bones work together to create movement?
A. Muscles are attached to bones by tendons. When a muscle contracts, it pulls on the bone, causing bending at a joint. To reverse the action at the joint, contraction of an opposing group of muscles occurs.
B. Muscles are attached to bones by ligaments. When a muscle contracts, it pulls on the bone, causing bending at a joint. To reverse the action at the joint, contraction of an opposing group of muscles occurs.
