Histology examines tissues at the microscopic level—the organization of cells into tissues and the surrounding extracellular matrix that gives tissues their structure and function. This field uses thin tissue sections and special stains to reveal how epithelial, connective, muscle, and nervous tissues are arranged in organs. By looking at how these tissues are built and interact, histologists learn how organs work in health and disease.

Cytology focuses on individual cells rather than the full tissue architecture, embryology studies the development of an organism from fertilization onward, and developmental anatomy looks at how body parts form during growth. The microscopic-tissue focus belongs to histology.
