1. Neurons Elaborate polarized epithelial cells with axon and dendrites
2. Epithelial cells Cells in tissues with polarized functions for absorption and secretion
3. a. Distinguishing When a neuroblast begins to differentiate into a neuron, the first process to occur
the apical do- is ______________?
main from the
basal domain a. Distinguishing the apical domain from the basal domain
b. Development of the primitive streak
c. Enlargement of the growth cone
d. Accumulation of actin and microtubule cytoskeleton
4. Neurites small extensions that protrude from the immature neuron (neither axon nor
dendrites)
5. Apical domain End of a neuron in which a single process becomes the axon which ends up
expressing Tau
6. Tau protein Microtubule-associated protein found in developing axon
7. Par-3 Polarity scaffolding protein crucial for axon development
8. a. right side de- Look at the image D; In red and green images, which side depicts what happens

of neurite growth growth
b. a post-mitotic neuroblast initiation the process of neurite growth
d. cellular differentiation where the cell matures and obtains its specialized function
