The eHistology SecondLook™ mobile application for the iPad is a study aid that provides a series of histology slides for users to self-test their level of knowledge and ability to recognize histological structures. The slides in the Michigan eHistology SecondLook™ application feature high quality images from the University of Michigan Medical School's Histology and Virtual Microscopy collection that are linked to questions about them. The eHistology application is free to download and comes with one slide deck. Additional slide decks can be purchased separately or as a set, and cover all major human tissues and organs. By taking a "Second Look" at these slides and answering the questions, users are able to review, self-evaluate, and test their knowledge of histology in order to be better prepared for exams.
