Question

Quizplus · Accepted Answer

Neurons are produced in the embryo's primitive neural tube during the prenatal period. This is where the process of neurogenesis occurs.

Answer: C
 Neurons in the prenatal period have not yet developed any connective fibers or axons that allow them to form connections with other neurons.

Answer: A
 During the prenatal period, neurons undergo mitosis, the process of cell division that produces two identical daughter cells from a single cell. This is how the neural tube grows and develops into the central nervous system.

Answer: D
 It is not accurate to say that neurons are seldom stimulated during the prenatal period, as they are constantly being influenced by various chemical and environmental factors. However, it is true that they are not yet receiving input from the outside world or processing information in the same way that they will once the nervous system is fully developed.
