Cytology is the study of the cells, especially their appearance and structure. Cells are the small parts that make up all living things, and their effects on each other and their environment. … Nucleus: directs the actions of the cell. Centrosomes: guides the cell in mitosis and meiosis, the processes for cell division.
What is the cytology simple definition?
Cytology is the study of individual cells of the body, as opposed to histology which is the study of whole human tissue itself. … This involves looking at the individual cells for abnormal changes of both the nucleus and also the cytoplasm (body) of the cell.
What is the best definition of cytology?

What does cytology mean in biology?
cytology, the study of cells as fundamental units of living things.
Why it is called cytology?
The discipline was founded by George Nicolas Papanicolaou in 1928. Cytopathology is generally used on samples of free cells or tissue fragments, in contrast to histopathology, which studies whole tissues. Cytopathology is frequently, less precisely, called “cytology”, which means “the study of cells”.

Is cytology part of pathology? Cytology (cytopathology) is a branch, or subspecialty, of pathology. In medicine, pathology deals with the laboratory examination of cells in samples of body tissue or fluids for diagnostic purposes.
How does cytology differ from cell and molecular biology?
Originally Answered: What is the difference between cell biology and cytology? Cytology is the branch of science which deals with the study of cell structure only whereas cell biology include the study of structure, function and reproduction of cell.
What is a cell?
In biology, the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body. A cell has three main parts: the cell membrane, the nucleus, and the cytoplasm. … A cell is surrounded by a membrane, which has receptors on the surface.
What do Cytopathologists do?
Cytotechnologists focus on a general variety of diseases found by using a microscope to detect abnormalities in human body cells. … Interpreting cells collected from cytological techniques, such as a Pap test, as normal or abnormal. Detecting changes in human cells that indicate cancer, disease, or other abnormalities.
What is histology in biology?
histology, branch of biology concerned with the composition and structure of plant and animal tissues in relation to their specialized functions. … The fundamental aim of histology is to determine how tissues are organized at all structural levels, from cells and intercellular substances to organs.
