Since the 19605, when eminent biologist Sydney Brenner established Caenorhabditis elegans as the premier model organism for neurobiology and development, substantial knowledge about the anatomical architecture of "the worm" has accumulated. Today, C. elegans is used by thousands of investigators in diverse fields, and it continues to provide a wealth of information about the fundamental principles of biology that apply to all animals.<BR>The beautifully rendered, true-to-life images contained in this Atlas illustrate in detail all of the internal and external structures of adult hermaphroditic C. elegans. Derived from the acclaimed online WormAtlas, C. elegans Atlas is a large-format, full-color laboratory reference tool designed for use at the bench and at the microscope. The Atlas is organized according to organ system, and the color-coded images are complemented with informative text and captions. C. elegans Atlas is an essential resource for students and working worm biologists in the fields of developmental biology, neurobiology, reproductive biology, gene expression, and molecular biology.
