In the myeloid stem cell pathway, which cells are characterized by the accumulation of cytoplasmic granules?

• A. Granulocytes
• B. Erythrocytes
• C. Megakaryocytes
• D. Monocytes

Answer: (A)

Verified step by step guidance

1. Understand the myeloid stem cell pathway, which differentiates into several types of blood cells including granulocytes, erythrocytes, megakaryocytes, and monocytes.
2. Recall that cytoplasmic granules are small particles found in the cytoplasm of certain cells, often containing enzymes or other substances important for the cell's function.
3. Identify which cells in the myeloid lineage are known for having abundant cytoplasmic granules. Granulocytes are named for their granules and include neutrophils, eosinophils, and basophils.
4. Contrast granulocytes with erythrocytes (red blood cells), which lack granules, megakaryocytes, which produce platelets but do not have granules in the same sense, and monocytes, which have fewer and less prominent granules.
5. Conclude that the cells characterized by the accumulation of cytoplasmic granules in the myeloid pathway are the granulocytes.
