SecondLook™ Needs Your Support:

Please support the SecondLook™ initiative with a donation to our Michigan Medicine SecondLook™ Donation Champaign(link is external). Your donation will enable us to update all existing SecondLook™ resources and to transform them into completely free Progressive Web Applications (PWA), including the SecondLook™Histology apps. It will also benefit the publication of several new topics (Hematology, Pathogen ID, and Gross Anatomy). Any size contribution is welcomed and will help us to provide these popular review tools to students at the University of Michigan and to many more worldwide.


Access to the supplemental resources for this session is password-protected and restricted to University of Michigan students. If you are a University of Michigan student enrolled in a histology course at the University of Michigan, please click on the following link and use your Kerberos-password for access to download lecture handouts and the other resources.
