Glial cells are the hidden champions of the brain! 🌟 They help make sure that neurons and synapses work the way they should. Let’s break it down into simpler parts:

1. Astrocytes:

   • They help control the levels of brain chemicals called neurotransmitters. 🧠
   • They keep a balance of ions, which is super important for sending electrical signals. ⚡
   • They create the blood-brain barrier, which protects our important neurons! 🛡️

2. Oligodendrocytes:

   • They cover axons (a part of neurons) with a protective layer. This layer makes signals travel faster and better! 🚀
   • They help keep neurons healthy and support their energy needs. 🍂

3. Microglia:

   • They act like the brain’s security team, cleaning up waste and fighting off germs. 🦠
   • They help shape the connections between neurons by getting rid of the ones that aren’t needed anymore! ✂️

All together, these glial cells are crucial for keeping the brain balanced and working well! 🎉
