For many decades myology teaching was traditional. The classical description of a muscle was of its belly followed by its tendon. The academic presentation on the blackboard and in all of the anatomy books consisted of the muscles origin, its direction and its insertion. The muscle belly was colored in red without any other details. It seems that these descriptions were negative and didn't allow one to understand the muscles intrinsic function. Micro-dissection has showed us that there are three essential notions which should be introduced: the muscle fascicle, the aponeurosis and the pennation. A new rehabilitation program for the musculoskeletal system must be based on knowledge of intrinsic anatomical structures. The notion of maximal stretching should be reconsidered due to the risk of sarcomere lesion. Muscle still ness is a concept that has not yet been elucidated and requires further research and clinical observation in physiotherapy practice.
