(These take a while to load - sorry.)

or of you missed the worm dissection, you may use these pictures and the
printed dissection guide to become familiar with worm anatomy and learn
some of the main concepts covered in the dissection. If you are unfamiliar
with the terms anterior, posterior, dorsal and ventral, please pause now
