Detailed explanation-1: -Glial (Neuroglial) cells do not conduct nerve impulses, but, instead, support, nourish, and protect the neurons. Glial cells are far more numerous than neurons and, unlike neurons, are capable of mitosis.
Detailed explanation-2: -Neuroglial cells are the nonconducting cells that support cells in the nervous system and help protect neurons, and they also help the neurons make the right contacts during embryonic development, others insulate axons.
Detailed explanation-3: -Glial cells help support, connect, and protect the neurons of the central and peripheral nervous systems. They come in many shapes, sizes, and types, each performing specialized functions. In the CNS, glial cells regulate neurotransmission and help form the blood-brain barrier.
