2PLatelets are formed on the surface of which cell type?
[blank_start]Megakaryocyte[blank_end] Cells- AMegakaryocyte
3Lifespan of certain cells:
Red blood cells = [blank_start]120 days[blank_end]

5Red cell precursors are called [blank_start]reticulocytes[blank_end]
- Areticulocytes
6From which progenitor cells do each of the following cell types arise?
B Cells - [blank_start]Lymphoid progenitor Cells[blank_end]
Neutrophil - [blank_start]Myeloid Progenitor Cells[blank_end]
Erythrocyte - [blank_start]Myeloid Progenitor Cells[blank_end]

- DLymphoid Progenitor Cells
- EMyeloid Progenitor Cells
- FLymphoid Progenitor Cells
- GLymphoid progenitor Cells
- HMyeloid Progenitor Cells
7Embryonically, haemopoietic stem cells originate in the [blank_start]mesoderm[blank_end]
- Amesoderm
- Bectoderm
- Cendoderm
8The first sign of erythroid activity as haemopoiesis occurs in the [blank_start]yolk[blank_end] sac
- Ayolk
9Haemopoiesis begins in which organ by week 6?
The [blank_start]liver[blank_end]
It then begins in the bone marrow by week [blank_start]16[blank_end]- A16
- Bliver
10In adults, haemopoiesis is restricted to the marrow within axial skeleton, pelvis and proximal long bones
- AVerdadero
- BFalso
11From which anatomical site is a bone marrow biopsy typically taken?
[blank_start]Posterior Iliac Crest[blank_end]- APosterior Iliac Crest
12In contrast to [blank_start]capillaries[blank_end], [blank_start]venous sinuses[blank_end] are larger and have a discontinuous basement membrane
- Avenous sinuses
- Bcapillaries
- Ccapillaries
- Dvenous sinuses
13The gaps between endothelial cells through which blood cells can enter the circulation are called [blank_start]fenestrations[blank_end]
- Afenestrations
14[blank_start]Red[blank_end] bone marrow is haemopoietically active
[blank_start]Yellow[blank_end] bone marrow is haemopoietically inactive and contains mostly fat- AYellow
- BRed
- COrange
- DRed
- EYellow
- FOrange
15There is an increase in [blank_start]yellow[blank_end] bone marrow with age
- Ayellow
- Bred
16[blank_start]Thrombopoietin[blank_end] regulates growth and development of megakaryocytes from their precursors
- AThrombopoietin
- BLymphopoietin
- CMegakarypoietin
17Label the cell types shown below (e.g. neutrophil, lymphocyte, eosinophil, basophil, etc)
- AEosinophil
- BLymphocyte
- CNeutrophil
18In terms of investigating haemopoiesis:
For [blank_start]non-lymphoid cells[blank_end], the full blood count and morphological assessment of blood cells is often sufficient for diagnosis
For [blank_start]lymphoid cells[blank_end], the expression of antigens indicating the lineage or developmental stage of the cell is required for diagnosis- Alymphoid cells
- Bnon-lymphoid cells
- Cnon-lymphoid cells
- Dlymphoid cells
19In order to investigate lymphocytes for diagnosis, a study of antigen expression using specific antibodies must be conducted. This process is called [blank_start]Immunophenotyping[blank_end]
- AImmunophenotyping
