Glial cells 20 years ago scientists did not think anything of glial cells, back then brain scientists did not have the technology that we do today. They believed there was no purpose for them; as time grew on the world has discovered new findings about neuroglial cells or more simplified as glial cells. Brain Scientists have learned that glial cells are by far different from nerve cells but they communicate with each other. Glial cells are a supporting factor for the synaptic interactions and electrical signaling, and happen to be smaller than neurons. The purpose for neuroglial cells is that; they surround the neurons and hold them in place, to supply nutrients and oxygen to neurons, and insulate one neuron from another making a barricade, also to destroy any pathogens and remove dead neurons. The 21st century or as I call it the new day in age, neuroscience has recognized glial cells to have some effects on certain physiological processes like breathing. Some glial cells are the basic back bones for neurons while other’s help maintain the internal environment of the brain.…show more content… It wasn’t until the 1900’s that it was discovered that glial cells hold neurons and keep them in place. In Greek terms the word glia means glue. Experiments didn’t really start until the 1960’s; before then the only thing scientists really understood about neurons was that they could not survive without glial cells. Neurons need to have glial cells to protect them. It wasn’t until the past couple of years that brain scientist have made the studies that glial cells play a huge part in the communication of the brain and development of human intelligence. Brain Scientists have also discovered that Glial cells cleanse the brain of
