Question

adult neural stem cells that eventually migrate to the olfactory bulbs are created at certain sites in the layer of cells lining the lateral cerebral ______________
neural tube
synapse
ventricles
cortex
vesicles

Explanation:

• Neural tube: It is an embryonic structure, not relevant to adult neural stem cell production for olfactory bulbs.
• Synapse: It is a junction between neurons for signal transmission, not a site for creating neural stem cells.
• Ventricles: The sub - ventricular zone (part of the ventricular layer) is a major site for adult neural stem cell production. These cells can migrate to the olfactory bulbs.
• Cortex: While the cortex has neural cells, it is not the primary site for the production of neural stem cells that migrate to the olfactory bulbs as described.
• Vesicles: These are small membrane - bound sacs for storage or transport, not a site for neural stem cell creation.

Answer:

C. Ventricles
