histology

This term describes the scientific study of tissues at a microscopic level, bridging the gap between gross anatomy and cytology. It focuses on the architectural arrangement of cells and the extracellular matrix to determine how structure relates to function. As a mass noun referring to a field of science, it is typically uncountable. When referring to the specific microscopic characteristics of a particular organ, it remains uncountable, describing the state or nature of the tissue rather than a discrete object.
