Which of the following refers to the study of the microscopic structure of tissue?

The study of the microscopic structure of tissue is known as histology. This field focuses on how tissues are organized and function at a microscopic level, examining their cellular structures, compositions, and relationships. Histology provides critical insights into how different types of tissues work together to form organs and systems within the body.

Microbiology, while related to the study of microorganisms, does not pertain specifically to the structures of tissues. Cytology is concerned with the study of individual cells, including their function and appearance, rather than the tissues that comprise those cells. Pathophysiology combines aspects of pathology and physiology, focusing primarily on the functional changes in the body that are associated with disease but does not involve the microscopic examination of tissue structure. Thus, histology is the correct term for the study in question.
