WebThe Complex Nature Of Astrocytes The Other Half Around 40% of all cells in the brain are a type of star-shaped glial cell called astrocytes. Astrocytes were first documented by neuroanatomists around 140 years ago, and for a long time were considered the “glue” that held the brain together. Glia, also called glial cells (gliocytes) or neuroglia, are non-neuronal cells in the central nervous system (brain and spinal cord) and the peripheral nervous system that do not produce electrical impulses. The neuroglia make up more than one half the volume of neural tissue in our body. They maintain homeostasis, form myelin in the peripheral nervous system, and provide support and protection for WebCells of the Human brain: The brain is composed of two types of cells i. nerve cells (neurons) and glial cells also termed as neuroglia or glia. 1. Nerve cells (Neurons): Neurons vary in shape and size, however they all consist of cell body, dendrites and axon. The neuron transmits the information via the electrical and chemical signals. deaf emergency communications
