19
Q

T of F: Reticulocytes have a nucleus

20
Q

Refers to the formation of WBC granulocytes

A

Granulopoiesis

21
Q

How do we distinguish granulopoeitic cells?

A
  1. Highly visible granules
  2. Varying nucleus shape
22
Q

How do we determine stage of development of granulopoiesis? Based on what?

A
  1. Type of granules
  2. Shape/segmentation of nucleus
23
Q

Familiarize the development of granulocytes specifically neutrophils (Or if you memorize it then slay)

A
  1. N. Promyelocyte
  2. N. Myelocyte
  3. N. Metamyelocyte
  4. N. Band

24
Q

Where are granulocytes stored?

A

Bone marrow

25
Where are WBCs formed?
Bone marrow
26
Two types of WBCs (granulocytes) in the blood according to function
Marginating cells and circulating cells
27
Familiarize the development of g aranulocytes specifically monocytes (Or if you memorize it then slay)
1. Myeloblast 2. Promonocyte 3. Monocyte (If it goes to the tissues, then: 4. Immature macrophage 5. Mature macrophage)
28
Refers to the formation of platelets
Thrombocytogenesis
29
Refers to the formation of both platelets and thrombus
Thrombopoeisis
30
Familiarize the development of platelets (Or if you memorize it then slay)
1. Megakaryoblast 2. Promegakaryocyte 3. Megakaryocyte 4. Platelets/thrombocytes
31
Refers to bone marrow whose color is produced by an abundance of blood and hematopoietic cells; found in newborns up to 3 years old
Red marrow
32
Refers to bone marrow filled with adipocytes that exclude most hematopoietic cells; found in individuals 10 years and up
Yellow marrow
