Histology and cytology seek to describe especially the structure of the tissues (histology) and cells (cytology) of animals and plants. Cytology is the study of individual cells of the body, as opposed to histology which is the study of whole human tissue itself.

In addition, cytology has recently made great progress with the discoveries of certain types of cancer the...
