What is the study of cells at a microscopic level called?

The study of cells at a microscopic level is called cytology. This field focuses specifically on the structure, function, and behavior of cells, exploring their internal components, such as organelles, as well as their interactions and roles in various biological processes. Cytology is significant in various areas, including medical diagnostics, where examining cell samples can help identify abnormalities, such as cancer.

Histology, while closely related, is concerned with the study of tissues rather than individual cells. Neurophysiology pertains to the functions of the nervous system, including the activity of neurons and their networks. Anatomy encompasses the study of the structure of organisms and their parts, which includes gross structural features rather than microscopic analysis. Therefore, cytology is the most accurate term for the microscopic examination of cells.
