White blood cells must undergo rapid changes in shape to squeeze through narrow capillary walls into infected tissues. Which cytoskeletal component enables this amoeboid movement?
Q1. White blood cells must undergo rapid changes in shape to squeeze through narrow capillary walls into infected tissues. Which cytoskeletal component enables this amoeboid movement?
Answer: Microfilaments
Explanation: Microfilaments (actin) are responsible for amoeboid movement and shape changes. Intermediate filaments are tempting but they provide static structural support, not movement.
