The primary tools used in histology include microscopes, histological stains, and microtomes. Microscopes, especially light microscopes, are fundamental for visualizing tissue sections. Electron microscopes are used for higher resolution studies. Histological stains such as Hematoxylin and Eosin (H&E) are used to differentiate between various tissue components. Microtomes are used to cut extremely thin slices of tissue for examination.
