Neuroglia

1. Functions: Support the metabolic and signaling functions of neurons;

2. participates in neuron circuit formation and synaptic plasticity;

3. axonal insulation (myelin);

4. contribute to the blood-brain barrier;

5. immune function;

6. formation of scar tissue

Components of neuroglia

• Astrocytes

• Oligodendrocyte

• Microglial cell

• Glial stem cell

• Oligodendrocyte precursor
