title: [Functional role of dragonfly legs before and after hatching: reorganization of coordinating interactions].
abstract: The characteristics of a structure-functional organization of leg apparatus were examined in the dragonfly Aeshna grandis: larvae of the final stadium, which legs perform a locomotion function and adults (imago) rising on a wing, which legs lose a locomotion function and are used mainly for catching a prey in the air. It has been demonstrated that legs of the imago practically do not differ from those of the larva either in shape or in proportion of segments of the leg and all changes in the functional role of legs of the imago are implemented due to modifications of mechanisms of limb muscle control and an appropriate reorganization or coordinating interactions. As it is proved by the obtained data, this reorganization concerns mechanisms of the generation of motor commands as well as close coordination of the activity of wing and leg apparatus and some others. The abovementioned mechanisms are discussed.
