| Term | Definition |
| formalin, alcohol, or freezing | type of fixative used to prepare tissue for light microscopy |
| osmium tetroxide | type of fixative used to prepare tissue for electron microscopy |
| protein | formalin fixes this type of substance |
| lipid | osmium tetroxide fixes this type of substance |
| perfusion and immersion | the two ways tissue can be fixation |
| perfusion | the fixative is injected into the blood vascular system |
| immersion | the tissue is immersed in the fixative |
| fixation, dehydration, embedding, sectioning, and staining | the first basic steps of tissue preparation |
