A Person May Have a Muscle Injury That Really Affects

A person may have a muscle injury that really affects the tendon and not the muscle tissue itself. Why is it that after a hard workout, muscle pain will go away in a few days at most, but tendinitis lasts so much longer?

A) Muscle cells are more elastic, so they are harder to damage.
B) Unlike a tendon, muscle tissue has an ample blood supply, so it's easier to repair.
C) Muscle cells can be rested, but tendons have to be used all the time.
D) The electrical signals that muscle cells generate are used to aid in healing.
