This 7th edition has been designed in such a way that it makes the subject of histology easily comprehensible for medical students. Th¬e basic principle of explaining the correlation between microscopic structure and function has been conserved in this edition as well. To keep pace with the recent trends, a description of microscopic structure has been supplemented with an appropriate explanation of the related molecular and cell biology. Wherever considered necessary, correlations of microscopic structure with clinical conditions have also been described. To facilitate comprehension of the subject, the text has been supported by a large number of images of microscopic slides, figures, and diagrams.
