Abstract

The following organs of Anodonta cygnea were investigated: oral palps; siphon; mantle; heart ventricle; central part of the intestine; gonads; kidney (Bojanus organ); statocyst; epithelium, musculature and excretory glands of the foot; hepatopancreas; adductor muscles and osphradium. It has been established that all basic types of tissues contain more or less cytosomes the structural composition of which is principially identical with those having been described and studied in detail within the nervous system. The cytosomes should be considered as generally occurring cell organelles in the tissues of Anodontn cygnea. A role is attributed to the cytosomes in the processes of anoxic energy production. The cytosomes show morphological and functional resemblance in many respects to the polymelanosomes of higher animals, although th ey contain no melanin but a lipochrome pigment having electron acceptor character.
