Distribution du système glio-interstitiel chez les Mollusques: Les parties tonique et phasique du muscle adducteur postérieur chezAnodonta

Summary The structure and nervous supply of the tonic and the phasic parts of the posterior adductor muscle ofAnodonta were studied by electron microscopy. A teloglia accompanies the nerves of the tonic part, while this tissue is absent from the phasic part of the muscle. This distribution is compared to the parallel situation in marine gastropods; and it is tentatively proposed that the development of the gliointerstitial tissue in the muscle of a mollusc depends on the type of contraction of this muscles and/or the development of the extracellular spaces.
