View Complete Answer & Explanation
Question (English)
Which of the following pair(s) related to blood cells is/are correctly matched?
- Band cells: young neutrophils only
- Segmented cells: mature neutrophils and Bird neutrophils: heterophils only
- Band cells: young neutrophils, Segmented cells: mature neutrophils, and Bird neutrophils: heterophils — all are correct ✓ Correct
- Band cells: mature neutrophils only
Explanation:
Correct Answer: All the above — all three pairs are correctly matched
Neutrophil Maturation Stages
- Band cells (Staff cells): Immature/young neutrophils; nucleus is unsegmented, band-shaped.
- Segmented cells (Polymorphonuclear/PMN): Mature neutrophils; nucleus is multilobed/segmented.
- In a 'left shift' (infection), band cells increase in blood → indicates the bone marrow is releasing immature cells rapidly.
Avian Blood Cells
- Heterophils: Avian equivalent of neutrophils in mammals.
- Birds have nucleated erythrocytes and nucleated thrombocytes (unlike mammals).
- Most numerous leukocyte in birds (as in ruminants, pig): Lymphocytes (60–65%).
- Most numerous leukocyte in horse, dog, cat: Neutrophils (60–65%).
