Which term describes lack of normal tone or tension in a muscle?

Explanation:
Lack of normal tone or tension in a muscle is described as atony. This means the muscle is flaccid and not taut even at rest, showing reduced or absent baseline tension. Muscle tone is the slight continuous tension that helps maintain posture and readiness; when that tone is lost, the muscle becomes floppy, which is what atony denotes. To check understanding, think of the other terms: atrophy is a loss of muscle mass rather than tone, myositis is inflammation of the muscle, and rupture is a tear in the muscle.
