Question

provide nourishment to neurons as well as insulate them and help repair damage. o dendrites o glial cells o axons o terminal buttons

Explanation:

To determine which structure provides nourishment, insulation, and repair to neurons, we analyze each option:

• Dendrites: Receive signals, not for nourishment/insulation/repair.
• Glial cells: Support neurons by nourishing, insulating (e.g., myelin), and repairing damage.
• Axons: Transmit signals, not the main support for nourishment/repair.
• Terminal buttons: Release neurotransmitters, not for support functions.

So glial cells match the described functions.

Answer:

O Glial cells
