Matured C. elegans sperm cells (spermatozoa) by scanning electron microscopy (SEM). The knobby projections to the right of the cell are called a pseudopod, which the cell uses to crawl. See also TEM (Transmission Electron Microscopy) image of C. elegans sperm cells.
C. elegans nerve system is labeled with GFP
to show the neuronal interconnectivity. C. elegans has a simple and well-defined nerve system that includes 302 neurons. See also more information on C. elegans neuron research. Courtesy of the C. elegans Worm Art Show.
This is the basic setup that researchers used to make the movies on this site. Image from DeVries, J.H., Thomas, C., White, J. (1996). Four-Dimensional Imaging: Computer Visualization of 3D Movements in Living Specimens. Science, 273, 603-607.
This figure shows one wild type (in upper left corner) and 5 locomotion defect worms. As you can see, the moving patten of mutants is different from wild type. This is to show how locomotion defect can affect worms’ motion.
