What is atrophy in terms of muscle condition?

Atrophy refers to the gradual wasting away or reduction in size of muscle tissue. This occurs when there is a lack of use or stimulation to the muscles, often due to inactivity, aging, or certain medical conditions. In the context of muscle health, atrophy is a significant concern because it can lead to weakness, decreased mobility, and a range of functional impairments. Understanding atrophy is essential for caregivers and health professionals, as recognizing it can help in implementing appropriate interventions to promote muscle use and prevent further deterioration. The other options describe muscle conditions that involve growth, preservation, or increased flexibility, which do not align with the definition of atrophy.
