Question 7

Steps of looking at cells in the body, e.g. liver cells.

3. Mount on medium for sectioning (often using paraffin wax block) and trimmed
4. Cut using a microtome sliding into 5-7 micro metre thick
5. sections of paraffin then floated on warm water bath and picked up onto glass slides, dried, wax removed, rehydrated and stained with histological stains
