Outnumbering neurons by up to 50 to 1, which cells protect, insulate, and reinforce neurons? sensory cells motor cells satellite cells astrocytes

The right answer is supporting glial cells.

Glial cells are localized in the nervous system. Their functions are to maintain the balance of neurons and produce myelin, which protects and isolates nerve fibers by providing them with the oxygen and nutrients they need to function.

Astrocytes (or satellite cells) mainly play a role in supporting and structuring the central nervous system. But they also have important functional roles. In particular, they participate in gliosis, a phenomenon that heals the lesions of the nervous system. They also intervene at the level of synapses to capture neurotransmitters, or at the level of the capillaries to ensure the blood-brain barrier. They also have a role in transporting molecules and supplying lactate neurons.

But they have not a role in protecting reinforcing and insulating neurons
