A

Yolk sac

25
Q

When a hematopoietic stem cell differentiates, it can give rise to what stem cells

A

Myeloid stem cell, B stem cell, T stem cell, and DC stem cell

26
Q

Wheb a late progenitor cell differentiates, it gives rise to

A

Precursor cell

27
Q

What are the stages of differentiation of proerythroblast

A

Basophilic erythroblast, polychromatophilic erythroblast, normoblas, and reticulocyte

28
Q

In thr erythroif lineage what are the stages capable of mitosis

A

Proerythroblasts and basophili erythroblasts

29
Q

This stage does not contain hemoglobin

A

Proerythroblast

30
Q

This stage synthesizes hemoglobin

A

Basophilic erythroblast

31
Q

This stage contain “checkerboard” chromatin but no nucleus

A

Polymatophilic erythroblast

32
Q

This stage contains a considerable amount of hemoglobin

A

Normoblast

33
Q

This stage prematurely enters the blood

A

Reticulocyte

34
Q

What are the stages of granulopoiesis

A

Promyelocyte, myelocyte, metamyelocyte

35
Q

This stage of granulopoiesis the nucleus is seen to be oval or round and it does not contain granules

A

Myeloblast

36
Q

This stage of granulopoiesis contains azuropilic granules (primary granules)

A

Promyelocyte

37
Q

Thid stage of granulopoiesis the promyelocyte acquire specific granules (secondary granules)

A

Neutrophilic myelocyte

38
Q

Nucleus is often U or S shaped or elongated and slightly curved

A

Stab cell or band form

39
Q

This has a presence of acidophilic granules and much larger than those in a neutrophilic myelocyte. No band formed

A

Eosinophilic myelocyte

40
Q

Their nucleus stain less intensely and finer chromatin granules. No band.

A

Basophil myelocyte and meta myelocyte

41
Q

Where did platelets come from

A

Megakaryocyte

42
Q

What are the stages of thrombopoiesis

A

Development of megakaryocyte, process of forming platelets from a megakaryocyte

43
Q

This stage of thrombopoiesis it has a large, slightly indented, ovoid nucleus that contain loose chromatin material and multiple nucleoli

A

Megakaryopoiesis

44
Q

It is a series of incomplete mitosis

A

Endomitosis

45
Q

Intermediage stage between megakaryoblast and adult megakaryocyte

A

Promegakaryocyte

46
Q

Process where cell forms long cytoplasm

A

Pseudopodia

47
Q

What are the stages of monopoiesis

A

Monoblast, promonocyte

48
Q

Thiis stage in monopoiesis begins to indent and the cytoplasm starts to manifest azurophilic granules

A

Monoblast

49
Q

Thid stage of monopoiesis is pler but still basophilic

A

Promonocyte

50
Q

What are the classification of lymphoid organs

A

Central lymphoid organs and peripheral lymphoid organs

51
Q

Composition of central lymphoid organ

A

Thymus and bone marrow

52
Q

Composition of peripheral lympois tissues and organs

55
Q

This stage of lymphopoiesis does not contain azurophilic granules and its nucleus is large and spherical

A

Lymphoblast

56
Q

This stage of lymphopoiesis is smaller and nucleus shows condensed chromatin and contains azurophilic granules

Q

It is any substance perceived by the cells of the lymphoid system as foreign to the body

A

Antigen

Q

These cells recirculate more often than B-cells
