As a result of a mechanical injury an over 10 cm long portion of a peripheral nerve was damaged. This caused an impairment of the upper limb activity. The patient was offered nerve transplantation. What glial cells will participate in regeneration and provide the trophism of the injured limb?

Answer options

1. Ependymal cells
2. Fibrous cells
3. Protoplasmic cells
4. Microglia
5. Schwann cells

Explanation

As a result of a mechanical injury an over 10 cm long portion of a peripheral nerve was damaged. This led to the impairment of the upper limb activity. The patient was offered nerve transplantation. What glial cells will participate in regeneration and provide the trophism of the injured limb?Schwann cells are known for their roles in the regeneration of damaged nerves. They participate in phagocytosis of axons of damaged cells and then guide regeneration by forming the Schwann tunnel.
