Question

Tissue injury causing redness, swelling, pain and production of heat and fever are localized manifestations of ___________ response.

• A. Physiological
• B. Anatomical
• C. Inflammatory
• D. Cellular

Hint:

Redness, heat, swelling, and pain are the four cardinal signs of inflammation.

Answer 1

The Correct Option is C

Step 1: Understanding tissue injury response.
When tissue is injured due to infection, trauma, or chemical agents, the body initiates a defense mechanism to limit damage and start repair.
Step 2: Features of inflammatory response.
The classical signs of inflammation include redness (rubor), swelling (tumor), pain (dolor), heat (calor), and sometimes fever. These are localized responses at the site of injury.
Step 3: Analysis of options.
(A) Physiological: Incorrect — too general and not specific to injury response.
(B) Anatomical: Incorrect — refers to structure, not response.
(C) Inflammatory: Correct — all listed symptoms are hallmark signs of inflammation.
(D) Cellular: Incorrect — inflammation involves tissues and mediators, not only cells.
Step 4: Conclusion.
The given symptoms are localized manifestations of an inflammatory response.
