Cell Specialisation and Organisation Flashcards
What’s cell differentiation controlled by
Cytoplasmic determinant
Induction
What’s determination and what does it result in
Initial change in stem cell
Results in gene expression for TSP
What does TSP do
determines structure + function of cell
What does cytoplasmic determinant do
Regulate gene expression
What’s induction
production and release of chemicals that signals change in gene expression in nearby cells
Which factor is more significant in differentiation
Induction
What are the two types of stem cells
Embryonic
Adult
What kind of stem cell is adult stem cell
Multipotent
What kind of stem cell is embryonic stem cells
Totipotent - early stage
Unipotent
Where are haemopoietic stem cells found
Bone marrow
How is does organisation happen
Axis development of embryo
Segmentation
Apoptosis
What does organisation mean
way in which specialised cells are grouped together to form tissues, organs and organ systems
What does axis development do
Determine which end of embryo is cranial/caudal, ventral/dorsal
What determines egg polarity
Cytoplasmic determinant
What are the four tissue types
Epithelial
Connective
Muscle
Nervous
What are the two major types of nervous tissue
Neurone
Glial cell
What are the 4 types of connective tissue
Bone
Blood
Fibrous
Cartilage
What are the 3 types of muscle tissue
Skeletal
Smooth
Cardiac
What are specialised glial cells called that from myelin sheath
Schwann cells
