What is the study of microscopic anatomy?

• A. Anatomy
• B. Histology
• C. Cytology
• D. Physiology

Answer: (B)

Microscopic anatomy refers to how cells and tissues are organized at a scale seen only under a microscope. This field is histology. Histology looks at the structure of tissues—the way cells are arranged, how they interact, and how different tissues come together to form organs. It relies on preparing thin tissue sections, applying stains, and examining them with light or electron microscopes to identify tissue types and architecture, such as epithelial layers, connective tissue, muscle, and nervous tissue. This is different from cytology, which studies individual cells in isolation; physiology, which focuses on function; and anatomy overall, which covers structure at both macroscopic and microscopic levels.
