This full-color photographic atlas provides clear photographs and drawings of tissues and organisms similar to specimens seen in a zoology laboratory. It is designed to accompany any zoology text or laboratory manual and delivers a balanced visual representation of the major groups of zoological organisms. More than 650 full-color, carefully labeled photographs, micrographs, and illustrations provide a visual reference for students in the lab. Several dissections of invertebrate and vertebrate organisms were photographed for this atlas. Sheep heart and brain dissections are also included. The terms used in this atlas match those appearing in commonly used college zoology texts. Clear, accurate, completely labeled figures are provided including life-cycle illustrations. Numerous dissections of invertebrate and vertebrate organisms are presented for students who have the opportunity to conduct similar dissections. Selected radiographs, CT scans, and MR images depict structures from living persons and thus provide an applied dimension to the human biology portion of the atlas.
