Meaning of Cytology
What is Cytology:
Cytology is the science that studies cells. It is also commonly known as laboratory tests to determine abnormalities in cells in a certain area of the body.
In biology, cytology is in turn known as cell biology. The cell is defined as the base unit of life by Robert Remak (1815-1865) in 1830, who would define the first postulate of the Cell Theory.
On the other hand, cytology is used in medicine to refer to the tests that are done on tissue samples in certain areas of the body. These samples are generally extracted with the technique known as exfoliative cytology and can be performed in the oral cavity, lungs, bladder or stomach.
Cytologies serve as a form of prevention, since the detection of cancer in its early stages is one of the keys to successfully combat it.
Cytology and cell biology
Cytology, also called cellular biology or cellular biochemistry, has the cell as its object of study. In this sense, cell biology and cytology are synonymous and can be used interchangeably.
Cytology is based on the 3 basic postulates of the Cell Theory established in 1855 and which stipulates the following:
- The cell is the base unit of life
- All life is made up of cells
- All cells come from a pre-existing
