KROK 1 2012 – Question 17 · KROK (Medicine) · Histology, Cytology, and Embryology
During postembryonal haemopoiesis in the red bone marrow the cells of one of the cellular differons demonstrate a gradual decrease in cytoplasmic basophilia as well as an increase in oxyphilia, the nucleus is being forced out. Such morphological changes are typical for the following haemopoiesis type:
- A. Lymphopoiesis
- B. Eosinophil cytopoiesis
- C. Neutrophil cytopoiesis
- D. Basophil cytopoiesis
- E. Erythropoiesis
Hint
Consider what accumulates in the cytoplasm of a maturing blood precursor so that its staining shifts from basophilic to oxyphilic, and what the expelled nucleus tells you about the end cell.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
