What are progenitor cells that produce neurons and glial cells called?

The correct choice identifies neural stem cells as progenitor cells that have the capability to produce both neurons and glial cells. Neural stem cells are unique in that they can self-renew and have the potential to differentiate into various types of neural cells, making them essential for neurogenesis during development and in certain regions of the brain throughout life. Their multipotent nature allows them to generate the diverse cell types necessary for proper functioning of the nervous system.

Other cell types listed, such as neural precursor cells, generally refer to the later stages of cell differentiation that occur after neural stem cells. Fetal stem cells and embryonic stem cells have broader differentiation potential and can give rise to many cell types, not just those related to the nervous system. Therefore, while all these cell types have important roles in development, neural stem cells are specifically designated for producing neurons and glial cells.
