Histology and cytology, studies of the chemical structure of subjects, may seem similar at first glance. However, they have different focuses, and cytology is a significantly narrower field of study than histology, covering a wide range of research. If you're wondering about the relative differences between cytology and histology, we'll help guide you through some of the critical distinctions between the two and applications for each.
What Is Histology?
Histology is a broad field that analyzes the microscopic chemical compositions and structures of tissues. This field looks specifically at animal and plant tissues and has historically been a key aspect of studying diseases.
Preparing slides in histology applications is a complex process involving these key steps:
- Fixing
- Processing
- Embedding
- Sectioning
- Staining
This process involves stringent requirements for proper procedure and can be time-consuming and costly. When followed correctly, however, it can yield highly beneficial results for the field.
In some cases, a tissue sample may be isolated and analyzed in a controlled environment for further observation. These cultures can provide insights into natural functions and chemical structures in plant and animal tissue.

What Is Cytology?
Cytology studies plant and animals cell structure and composition. It examines several different properties of cells, including:
- Cell physiological features
- Cell structure
- Cell life cycle
- Cell function
- Cell interactions
- Cell constituents
- Cell division
- Cell death
Essentially, cytology examines the cell's complete life cycle and function, studying how it operates over time. This field is particularly applicable for analyzing cell diseases. Its primary branches of study include cell biology, cytopathology and cytogenetics.

Histology Vs. Cytology
In terms of general practices, histology and cytology have some fundamental similarities. They are both fields essentially based on biology, and they provide detailed insights into the microscopic components of animal and plant properties. As you study these properties, you can see that they are both critical to the scientific study of disease.
However, in practice, histology and cytology look significantly different. Several differences in applications and techniques distinguish the two fields from one another:
- Focus: Histology focuses on the chemical composition and function of tissues, while cytology looks more at the structure and function of living organisms' cells.
- Scope: Cytology focuses on a narrow specialized field, while histology is a much broader field covering several areas of study.
- Slide Preparation: Preparing slides for histology is quite complex, while the procedure is far more straightforward in cytology.
- Expenses: While cytological techniques are relatively inexpensive and straightforward, histological methods require more complexity and cost more.
Overall, when discussing cytology vs. histology, the two fields overlap in terms of what they study, but their uses and practices set them apart.
