Two proginetor cells
- B.
A proginetor cell and a brain cell

- D.
Two brain cells
- 21.Radial glia are necessary because ________________.

They make sure the dura mater meninge doesn't shrink or collapse on itself
- B.
Provide nourishment to the pia mater
- C.
Guide neurons toward the layer of C-R cells
- D.
They do not serve a purpose anymore, they do for simpler species but are just an evolutionary byproduct in humans
- 22.The last layer of neurons to form the cerebral cortex is _________________.
- A.
Closest to the center of the brain
- B.
Closest to the layer of C-R cells
- C.
Near the front of the brain (because it's the most recent evolutionary adaptation)
- D.
Near the hindbrain (because it's the oldest evolutionary adaptation)
- 23.When the proginetor cells receive a signal to begin apoptosis this means they ___________.
- A.
Begin symmetrical division
- B.
Begin asymmetrical division
- C.
Die
- D.
Turn into phagocytes
- 24.The axons of approximately 50 percent of neurons in the ventricular zone die, how come?
- A.
The brain's complexity continues to develop but the skull isn't growing at the same rate (hence the curved cerebral cortex), so there isn't room for all those neurons.
- B.
The axons have to travel relatively far within the brain and many die of lack of nutrition before they make their connections
- C.
It makes more sense to make too many neurons and let them battle out for the highest efficiency than to make just the right amount of each neuron.
- D.
If the axon of a neuron attaches to the incorrect part of the brain then the postsynaptic cell tells it to die
