What are the distinguishing characteristics of three granulocytes (neutrophils, eosinophils and basophils)? Where are they found and how are they activated and regulated during an immune response?
Which of the following statements is NOT CORRECT regarding hematopoiesis? Select one:
a. Erythropoiesis requires vitamin B12, folate and iron.
b. Monocytes are part of the lymphoid lineage.
c. Granulocytes include basophils that release histamine.
d. Thrombopoietin stimulates the formation of platelets.
This question arises because I saw that monocytes and leukocytesare commonly called 'mononuclear cells' in the scientificliterature. The implication of course being that other immunesub-types are multi-nuclear!
I know of granulocytes (e.g. neutrophils) that are classed as'polymorphonuclear' because their nuclei are segmented, and canalter their shapes, and muscle cells that fuse together to form onelong cell (muscle fiber) with multiple nuclei. What other examplesof multi-nucleated cells are there?
I am also interested in the advantages gained by cells havingmultiple (or segmented) nuclei?
