diFiore’s Atlas of Histology with Functional Correlations explains basic histology concepts through realistic, full-color composite and idealized illustrations of histologic structures. Added to the illustrations are actual photomicrographs of similar structures. This unique approach has become a popular trademark of the atlas. In addition, all structures are directly correlated with the most important and essential functional correlations. This approach allows students to efficiently learn histologic structures and their major functions at the same time. This atlas is used by various students in their histology course, including medical, graduate, and undergraduate sciences.
