Adult ALM touch dendrite (tomography)
3D model produced from a dual-axis electron tomogram of a high pressure frozen adult nematode (wild type). Large caliber microtubules are marked in purple, ribosomes in red, smooth ER in yellow, vesicles in blue, ALM plasma membrane in green, and hypodermal membrane in brown. The movie shows the annotated objects (in color) while panning through 753 steps in the z-dimension of the calculated tomogram (cf. OToole and Muller-Reichert, 2009). The total depth in z is about one micron. No microtubules reach an endpoint within the stack. This is perhaps the first demonstration of ribosomes within an ALM dendrite (cf. Rolls et al., 2002). Electron microscopy by KD Derr, using Technai 20 TEM at NYSBC. Tomogram production using Protomo by Bill Rice. Annotation by Kristin A. Politi, using IMOD. Rendering and animation by Chris Crocker and Kevin Fisher, using Amira.

 MVB in C. elegans (tomography)
3D model produced from a dual-axis electron tomogram of a high pressure frozen adult nematode (wild type). The multivesicular body in lateral hyp7 shows internal vesicles in pink, outer membrane shell in orange, ribosomes in red, microtubules in green, and hypodermal plasma membrane in yellow. The movie combines the annotated objects (in color) with several pans through about 100 steps in the z-dimension of the calculated tomogram (cf. O’Toole and Muller-Reichert, 2009). The total depth in z is about 100 nm. Electron microscopy by KD Derr, using Technai 20 TEM at NYSBC. Tomogram production using Protomo by Bill Rice. Annotation by Kristin A. Politi, using IMOD. Rendering and animation by Chris Crocker and Kevin Fisher, using Amira.

 Serial block-face imaging of C. elegans midbody
Serial block-face imaging using the “3View” ultramicrotome inside a scanning electron microscope chamber (SBFSEM) has been used to produce a movie travelling through the midbody of an adult C. elegans. We thank Joel Mancuso at Gatan for providing this movie to WormAtlas. On the WormAtlas methods pages, we offer advice on how to best prepare nematode tissues for block-face imaging.

FIB/SEM movie of L1 nerve ring
Wild type L1 head was milled in 10 nm steps through a portion of the nerve ring. The animal is rotated so that ventral axis is to the upper left corner. The first image begins in the retrovesicular ganglion, and the movie proceeds anteriorly through the entire nerve ring. Tissue was fixed using an OTO protocol by Ken Nguyen, and images were acquired on the FEI Helios FIB/SEM microscope at the New York Structural Biology Center by Dr. William Rice. For more details see FIB/SEM methods page.

 Animation of hermaphrodite gonadogenesis
Click on animation to open movie. Press "Play" to start,"Pause" to stop or click boxes to view specific stages. Yellow, germ nuclei; Red , DTC nuclei; Purple, other early somatic cell nuclei. As germline development proceeds, mitotic nuclei remain yellow, while green represents meiotic stages (light green for early stages (leptotene and zygotene) and darker for later stages (pachytene)). Blue, spermatocytes; Dark Blue, mature sperm; Pink, oocytes. (note: one gonad arm is depicted but the other develops in the same way). (Image source: E. J. Hubbard. Animation by Rob Stupay © 2003.)
