The fine organization of the cerebral ganglion of acanthocephalan Corynosoma strumosum, at the stage of the late acanthella, from the paratenic (reservoir) host White Sea cod Gadus morhua, which differs from the sexually mature form only by the proboscis inserted into the sheath is investigated. Ganglion of Acanthocephala is located in the posterior third of the vaginal cavity of the proboscis between the fibers of the retractor muscles. During the activity of the retractor muscles, the cerebral ganglion is constantly subjected to strong deformation. The cerebral ganglion of Acanthocephala is separated from the cavity of the proboscis sheath by a thin layer of integument, which consists of a dense network of fibrils associated into bundles or scattered in the main substance of considerable electron density. Ganglion of Acanthocephala consists only of nerve cells. On the periphery of the cerebral ganglion the bodies of nerve cells are located, and the inner zone of the ganglion is occup
