Nervous and muscle systems of lower bilateral animals (Xenacoelomorpha)

2

The collection contains images of temporary whole mount preparations. The images were taken by confocal laser scanning microscopy. The preparations were created using immunohistochemical staining of nervous elements for serotonin and FMRFamide and histochemical staining by phalloidin for muscles. The collection includes images of the central and peripheral nervous systems and neuromuscular interactions in 10 species from 5 families and 3 classes of Xenacoelomorpha. The work was performed at the Åbo Akademi (Finland). The images are kept on the server of the Zoological Institute RAS (Laboratory of Evolutionary Morphology) and are available from the author.
