This atlas provides a detailed insight into the complex structure and organization of cells and tissues, and highlights their specific functions as well as the dynamics of diverse intracellular processes. Highly informative electron micrographs are complemented by explanatory texts, selected references and schemes. The concept that subcellular organelles provide the structural foundation for fundamental processes of living organisms is emphasized. The first part covers the cellular organelles and changes caused by experiments or occurring under pathological conditions. The second part employs selected examples to illustrate the principles of functional tissue organization and typical changes resulting from experimental induction or pathological situations.
