 | | Many different medical conditions cause muscle shrinkage, or atrophy, such as when a patient suffers from cancer or AIDS, or simply when a limb is casted following injury, or even when a patient undergoes prolonged bed rest. |
 | | Furthermore, the normal atrophy that accompanies aging, termed sarcopenia, can contribute to debilitating fraility in older patients. |
 | | Muscle size is maintained by a balance between processes that promote muscle growth via increasing protein synthesis, and processes that cause muscle atrophy by initiating protein degradation. |
