[Functional anatomy of the feeding apparatus of the mallard (Anas platyrhynchos L.) structure, movement, electro-myography and electro-neurography (author's transl)].

A causal model for the functioning of the beakapparatus of the mallard during straining is formulated on a qualitative basis. The starting point for this model is an abstraction of the analysed structure of the muscle, bone, ligament system. The system was studied by electromyography and cinematography of the movements. It was attempted to quantify the model. Connections with neurography are shown.
