In physiology, medicine, and anatomy, muscle tone (residual muscle tension or tonus) is the continuous and passive partial contraction of the muscles, or the muscle's resistance to passive stretch during resting state.[1][2] It helps to maintain posture and declines during REM sleep.[3] Muscle tone is regulated by the activity of the motor neurons and can be affected by various factors, including age, disease, and nerve damage.
