Hemopoiesiz Flashcards
It is the process of producing the formed elements
Hemopoiesis
What comprises the hemopoiesis
erythropoiesis thrombopoiesis granulopoiesis monopoiesis lymphopoiesis
Blood cell formation is the function of what
Mesoderm of the yolk sac
Where does lymphopoiesis occur
bone marrow
lymphoid tissues
What are the kinds of hemopoietic tissue
lymphoid and myeloid tissue
Where is myeloid tissue produced in newborns
red bone marrow
What is replaced by red bone marrow when bones increase in size
adipose and yellow marrow
It is made up of reticular fibers and reticular cells. Supporting framework of connective tissue
Stroma
Functional elements of a tissue or organ
Parenchyma
They are responsible for removing foreign particulate material and worn out RBC from the blood and marrow cavities
Persinusoidal macrophages
What kind of stem cell is zygote
Totipotent stem cell
These are cells that arise during the first few days of embryonic development
Blastomeres
Development of spherical structure
morula
Fluid-filled sphere in the fourth intrauterine life. True totipotent stem cells do not exist anymore.
Blastocyst
It is a form of blastocyst that forms the enclosing wall or
Trophoblast
The trophoblast of thr blastocyst gives rise to
Placenta and fetal membranes
This type of blastocyst forms a cluster of cells
Inner cell mass
The inner cell mass or embyonic stem cells give rise to
Fetus
They are versatile cells that can transform into numerous cell types very fast
Multipotent stem cells
What does the mesenchymal cells produce
Bone, cartilage, muscle and certsin connective tissue
What does neuronal stem cells produce
Neurons
What does glial stem cells produce
Glial cells
What does hematopoietic stem cell produce
Formed elements
