Histology is the study of what type of material?

• A. Living tissue
• B. Cells
• C. Nervous system
• D. Digestive system

Answer: (A)

Histology is the study of living tissue—the microscopic structure formed by groups of cells and their surrounding extracellular matrix. By examining thin, stained tissue sections under a microscope, we learn how cells arrange themselves into tissue types such as epithelium, connective tissue, muscle, and nervous tissue, and how this organization supports function. This focus on tissues, rather than on individual cells or entire organ systems, is what sets histology apart. So the best description is that histology investigates the microscopic architecture of living tissue.
