Part 2: PBI288 midterm Flashcards
What is the all of nothing law (related to AP)
Once an AP is triggered it cannot be stopped.
What does an AP largely depend on
Movements of K+ and Na+
What does the neural tube come from
Neural grooves (once it closes)
What forms the neural grooves
The neural plates folds inwards creating the groove.
What is the most common birth defect called
Neural Tube defects
What does Neural Tube Defect lead to
Anencephaly and spina bifeda
How many structures are derived from the neural tube at 4 weeks of gestation
3
What are the 3 divisions of the neural tube at 4-weeks
1) Prosencephalon (forebrain)
2) Mesencephalon (midbrain)
3) Rhombencephalon (Hindbrain)
At week 7 of gestation, how many structures is there
1) Telencephalon
2) Diencephalon
3) Mesencephalon
4) Metencephalon
5) Myelencephalon
What are the 4 major steps of cellular behavior
1) Proliferation
2) Determination
3) Migration
4) Differentiation
What is proliferation
Increase the number of cells once that neural tube is complete.
What is determination
Cells will determine their destiny into becoming neurons or glial cells.
What is Migration
Neurons will proliferate and migrate to their final location
What is differentiation
Stem cells become specialized
What does the growth cone indicates
How axon develop
