Tissue morphology examines the microscopic structure of cells, tissues, and organs and links these patterns to function and disease processes. This book guides readers through histology techniques, staining methods, and morphometric analysis used in both research and diagnostic labs. It explains how to interpret cellular architecture, identify pathological changes, and quantify tissue features with modern imaging tools. Practical chapters include sample preparation, artifact recognition, and basic image analysis workflows. Photomicrographs, annotated diagrams, and measurement examples make abstract concepts concrete. Useful for pathologists, biomedical researchers, and advanced students, it connects microscopic form to biological meaning.
