Glial cell: A supportive cell in the central nervous system -- the brain and spinal cord. Glial cells do not conduct electrical impulses (as opposed to neurons, which do). The glial cells surround neurons and provide support for them and insulation between them. Glial cells are capable of extensive signaling in response to a diversity of stimuli. Bidirectional communication exists between glial cells and neurons, and between glial cells and vascular cells.
Glial cells are the most abundant cell types in the central nervous system. There are three types of glial cells: astrocytes, oligodendrocytes, and microglia. Astrocytes are concerned with neurotransmission and neuronal metabolism. Oligodendrocytes are involved in the production of myelin, the insulating material around neurons.. And microglia are part of the immune system.
Glial cells, commonly called neuroglia or simply glia, are one of two major classes of cells in neural tissues, the other being neurons, for which the glial cells provide ...
Glial cells, sometimes called neuroglia or simply glia (Greek. Î³Î»Î¯Î±, Î³Î»Î¿Î¯Î± "glue"; pronounced in English either or ), are non-neuron. al cells
n. A type of neuroglia cell lining the central canal of the spinal cord or the brain. A cell of the ependymal area of the developing neural tube.
Glial cell: A supportive cell in the central nervous system -- the brain and spinal cord. Glial cells do not conduct electrical impulses (as opposed to neurons, which do).
Although there are about 100 billion neurons in the brain, there may be about 10 to 50 times that many glial cells in the brain. (New research suggests the neuron-to-glia ...
