A person who studies tissues is called a what?

• A. Pathologist
• B. Histologist
• C. Biologist
• D. Anatomist

Answer: (B)

Studying tissues is the work of histology, so the person who specializes in this area is a histologist. Histology looks at the microscopic structure of tissues—the arrangement of cells, the fibers of the extracellular matrix, and how different tissue types form the lining and support of organs. Histologists often prepare tissue sections, stain them to reveal cellular details, and analyze how tissues are organized and how they function in health.

This designation differs from a pathologist, who is typically a medical doctor diagnosing disease by examining tissues and body fluids. It also differs from a biologist, whose study covers many aspects of life, not necessarily focusing on tissue microstructure, and from an anatomist, who tends to emphasize the macroscopic organization of the body and organs rather than the microscopic tissue architecture.
