Histology focuses on:

• A. Studies microscopic tissues of the body.
• B. Studies the function of tissues.
• C. Studies large organs.
• D. Studies developmental changes.

Answer: (A)

Histology focuses on the microscopic structure of tissues—the way cells are arranged and interact with their surrounding extracellular matrix, observed with microscopes and often stained to reveal detail. This field aims to understand how tissue architecture underpins function, at a level smaller than whole organs. The other options describe different areas: physiology deals with how tissues and organs function; gross anatomy looks at large structures without magnification; embryology studies development and changes from conception onward. So the best fit is the study of tissues as seen under the microscope.
