MUSCLE PHYSIOLOGY

Detailed explanation-1: -Disuse (physiologic) atrophy is caused by not using your muscles enough. If you stop using your muscles, your body won’t waste the energy it needs to take care of them. Instead, your body will start to break your muscles down, which causes them to decrease in size and strength.

Detailed explanation-2: -atrophy, decrease in size of a body part, cell, organ, or other tissue. The term implies that the atrophied part was of a size normal for the individual, considering age and circumstance, prior to the diminution.

Detailed explanation-3: -Disuse atrophy is a type of muscle atrophy, or muscle wasting, which is a decrease in the size of muscles in the body. Disuse atrophy can occur when a muscle is no longer as active as usual. Muscles that are no longer in use will slowly become weaker and eventually, they begin to shrink.

Detailed explanation-4: -Atrophy is defined as a decrease in the size of a tissue or organ due to cellular shrinkage; the decrease in cell size is caused by the loss of organelles, cytoplasm and proteins.
