Histology ImageReview was created with the purpose of providing students with a systematic review of cell and tissue biology and organ histology. It offers several different magnifications of a structure, tissue or organ as if the student were using a microscope in the histology laboratory.  In addition, Histology ImageReview contains selected clinical correlations which augment basic histological information. Furthermore, the program provides a mechanism for self-assessment employing image-based questions and learning responses.
