The term for the study of tiny structures found in living tissues is histology. Histology involves examining the microscopic anatomy of cells and tissues to understand their structure, function, and organization. This field is essential in medical science because it helps in identifying healthy and diseased tissue, contributing to diagnosis and treatment in various medical conditions.

Other related fields like pathology focus on the study of diseases and often involve histological examination to assess tissue changes associated with various conditions. Physiology, on the other hand, is concerned with how organs and systems function, rather than their microscopic structures. The nervous system as a term refers specifically to a collection of organs and cells that transmit signals throughout the body, not the study of tiny structures in tissues. Therefore, histology is the most precise term that captures the examination and analysis of microscopic components in living organisms.
