Which term describes the shrinking of muscle mass due to protein deficiency and decreased exercise?

• A. Bradycardia
• B. Atrophy
• C. Tachycardia
• D. Care Plan

Answer: (B)

Muscle atrophy is the shrinking of muscle mass due to inadequate protein intake and reduced activity. When protein intake is low, the body has fewer amino acids to maintain muscle proteins, and with little exercise or use, the production of new muscle protein slows while existing proteins may be broken down. The result is smaller muscle fibers and less overall muscle mass. This is a common effect of disuse combined with malnutrition. By contrast, bradycardia and tachycardia refer to heart rate changes, and a care plan is simply a plan of care, not a biological change in muscle.
