Question

Regrowth of axons from nerve cells in peripheral ganglia or those located in the central nervous system that had its peripheral axons severed can only occur by having what two requirements?

A. Reactivation of developmental processes and initial synapse formation.
B. Restoring functional integrity and regrowth of existing glial cells.
C. Retaining neural stem cells and being present in environment acceptable for differentiation and production.
D. None of the above statements are correct.
E. All of the above statements are correct

Answer 1

The regrowth of axons requires reactivation of developmental processes and initial synapse formation, making option A the correct answer. Glial cells such as Schwann cells and oligodendrocytes also contribute to the process by forming the myelin sheath.

Step-by-step explanation:

The regrowth of axons from nerve cells in peripheral ganglia or those located in the central nervous system (CNS) that had its peripheral axons severed requires reactivation of developmental processes and initial synapse formation. So, the correct answer is A. Reactivation of developmental processes and initial synapse formation.

This process can be facilitated by glial cells such as Schwann cells in the peripheral nervous system (PNS) and oligodendrocytes in the CNS. These cells can aid in insulating the axon to restore the myelin sheath, which is essential for efficient signal conduction. The environment also plays a significant role in axon regeneration, requiring an environment conducive to differentiation and axon growth.
