title: Basic physiologic notions with regard to the musician's hand.
abstract: This article presents a three-level study of the motor action, from the simple to the more complex, and investigates at each level the possibility of an unexpected functional anomaly. The first level is referred to as elementary, corresponding to the physiology ofthe neuron and the muscular fiber. The second level includes the anatomic, determined connections. It permits one to understand how the nervous "machinery" works, indeed unconsciously, but allowing many adaptations. Finally, on the third level the author approaches the most complex level the physiology of the brain, the starting point of movement and the convergence point of all information.
