What does histology study?
organs
tissues
cells
joints
The Correct Answer is B
A. organs: Histology is concerned with microscopic structure - organs are macroscopic structures composed of tissues, so this is not the best definition.
B. tissues: Histology is the study of tissues (their cells and extracellular matrix) and how they are organized.
C. cells: The study of individual cells (their structure/function) is cytology; histology examines cells within the context of tissues.
D. joints: Joints are anatomical structures (arthrology); they are not the primary focus of histology.

Correct Answer is B
Explanation
A. sutured surgical wound: Sutured wounds have edges approximated and heal by primary intention (direct epithelialization with minimal scarring).
B. stage IV ulcer: Stage IV pressure/decubitus ulcers have large tissue loss and damaged margins so they heal by secondary intention (granulation, contraction, lots of scar tissue).
C. sunburn: Superficial epithelial injury (sunburn) typically heals by regeneration of epithelium, not secondary-intention wound healing.
D. paper cut: Small clean lacerations with approximated edges heal by primary intention after closure (or spontaneously with minimal scarring).
