Which of the following blood cells is known as PMNL (Polymorphonuclear leukocyte)?
Show Hint
PMNLs mainly refer to neutrophils, the first line of defense in our immune system.
Updated On: Oct 16, 2025
- Lymphocyte
- Monocyte
- Neutrophil
- Platelets
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding PMNL.
PMNL stands for Polymorphonuclear leukocytes, which are a type of white blood cell characterized by a nucleus with multiple lobes.
Step 2: Role of neutrophils.
Neutrophils are the most abundant PMNLs and play a major role in the innate immune system by engulfing pathogens through phagocytosis.
Step 3: Elimination of wrong options.
(1) Lymphocytes: Mononuclear, not PMNL.
(2) Monocytes: Also mononuclear, not PMNL.
(3) Neutrophils: Correct, they are polymorphonuclear.
(4) Platelets: Not cells but fragments, hence not PMNL.
Step 4: Conclusion.
Thus, the correct answer is (3) Neutrophil.
