In addition to playing a role in hemostasis, platelets have the ability to:

a. stimulate bone marrow production of erythrocytes.
b. release biochemical mediators of inflam-mation.
c. undergo cell division in response to bleeding.
d. activate a humoral response.

ANS: B
Platelets contain cytoplasmic granules capable of releasing proinflammatory biochemical media-tors when stimulated by injury to a blood vessel. Platelets assist with inflammation; they do not produce erythrocytes, undergo cell division in response to bleeding, or activate the humoral re-sponse.
