All about A/P axis
The vertebrae is patterned along this axis
What is the A/P axis
This structure is necessary for the formation of the Floorplate and motor neurons
What is the Notochord
True or False, Cells with different morphologies can arise from the same progenitor
What is true
This type of cell division is required for neurogenesis in the cortex
What is asymmetric cell division
This protein inhibits Notch leading to a decreased expression of SuH and an increased expression of Neurogenin
What is Numb
What happened when Cerberus (Wnt inhibitor) was injected into a tadpole?
What is ectopic head formation

What is dorsal
Using a retrovirus to label lineages of cells is a good method for what?
What is tracking the daughter cells of progenitors
Neighboring cells can influence each other’s fate through this type of signaling
What is Notch signaling
Activating Delta in one cell leads to excess signaling of _____ in the other cell
What is Notch
Dkk1 mutants have severe ___ defects
what is brain
Is BMPR1 a or b expressed in the Central nervous system?
What is BMPR1b
This part of the brain is unique to mammals and is involved in higher- order brain functions
What is the Neocortex
If the mitotic spindle is horizontal this will result in which type of division
What is symmetric division
A daughter cell that inherits Numb from a precursor cell will have this fate
What is becoming a Ganglion Mother Cell or neuron
This gene induces the midbrain
what is Fgf8
In the absence of this type of signaling dorsal cells are able to change their fate.
What is BMP signaling
What type of movement has Nuclei move to the inner ventricle surface just before mitosis?
What is Interkinetic nuclear migration
This type of inheritance of Numb is one way to trigger differences of Notch signaling between siblings
What is Asymmetric inheritance

what is ventral serotonergic neurons
Neurons born in ventrical zone migrate along radial glial fibers to this location
What is the outer cortical layer
This is the differentiation of cells into specialized tissues and organs during growth
What is histogenesis
Notch signaling can mediate this in several stages of neurogenesis
What is cell fate
