Secondary motor neurons in a male western mosquitofish (Gambusia affinis affinis) spinal cord.

Secondary motor neurons in a spinal cord whole mount of a male western mosquitofish (Gambusia affinis affinis) that have been labeled with lysine-fixable 3000 MW Texas Red® dextran (Cat. No. D3328). The dextran crystals were applied to the bipinnate inclinator muscles of the anal appendicular support fin, and the dye was transported from the axons to cell body and dendrites. Motor neurons were visualized and photographed through a bandpass optical filter appropriate for Texas Red® dye, by epifluorescence microscopy. Image contributed by E. Rosa-Molinar, University of Nebraska Medical Center, and Bernd Fritzsch, Creighton University.
