The Hematology Challenge
The Hematology Challenge
Test your knowledge about blood, its components, and the fascinating processes that govern hematopoiesis. This quiz is designed for anyone interested in the intricacies of the blood system, from students to professionals.
- Explore key concepts in hematology
- Enhance your understanding of leukocytes, erythrocytes, and megakaryocytes
- Learn about the embryonic development of blood cells
Which of the following statements about blood is/are true?
The reticulocytes are not fully mature erythrocytes
Membrane of normal erythrocytes has high flexibility.
Leukocytes are the predominant cells of blood.
Serum contains fibrinogen.
Which parts includes stromal part of bone marrow?
Megakaryocytes.
Adipocytes.
Retucular cells.
Stem cells.
Macrophages.
Platelets.
Osteoclasts.
Reticulocytes.
Which statements regarding leukocytes are correct?
Basophils are the least numerous white blood cells.
Monocytes differentiate into macrophages.
Neutrophils are the largest leukocytes with basophilic cytoplasm and kidney shaped nuclei.
Monocytes make up about 25-35% of leukocytes.
What is true about megakaryocytes?
Are cytoplasmic remnants of monocytes.
Circulate in blood.
Are the least numerous white blood cells.
Have poliploid nucleus.
What is true about the neural crest?
The neural crest originates form cells located along the lateral margins of the neural plate.
Neural cells arise as a result of an inductive action by neuroectoderm.
Neural cells arise as a result of an inductive action by non-neural ectoderm.
The neural crest originates from mesoderm.
Which molecules are permissive for neural crest cells migration?
Ephrin B1.
Molecules present in basal lamina.
Type IV collagen.
Chondroitin sulfate proteoglycans.
What is true about hemopoiesis?
Hemopoiesis depends on a microenvironment with specific endocrine, paracrine and juxtracrine factors.
Red blood cells develop from myeloid cell.
Hemopoiesis occurs in the bone marrow of children and adults.
Hemopoiesis growth factors stimulate proliferation of progenitor and precursor cells.
What is true about platelets and its formation?
After platelets formation megakaryotes undergo apoptosis
Processes of the megakaryotes are called proplatelets
Reduction in the number of circulating platelets is call thrombocytopenia
Platelets are produced under influence of thrombopolrtin
What is true about platelets?
Platelets produce blood-clotting factors
Promote blood clotting
Have kidney-shaped nucleus
Are cytoplasmic remnants of monocytes
Contain granules, mitochondria, glycogen
Which connection: blood cells and their feature is/are true?
Eosinophils – increase in number during parasitic infestation
Erythrocytes – determination of blood groups
Basophils – clotting of blood
Lymphocytes B – have no nucleus
Lymphocytes – fat storage
Which of the following statements about erythrocytes is/are true
Transport of oxygen and carbon dioxide
Hemoglobin of erythrocyte is protein specialized for transport of oxygen and carbon dioxide
No nucleus
Can leave the blood vessels by diapedesis
Where are formed blood cells during embryonic development respectively (in correct order) formed?
Yolk sac, liver, AGM, bone marrow, spleen
AGM, yolk sac, liver, spleen, bone marrow
AGM, liver, bone marrow, spleen
Yolk sac, AGM, liver, spleen, bone marrow
