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: -astrocyte: glial cell in the central nervous system that provide nutrients, extracellular buffering, and structural support for neurons; also makes up the blood-brain barrier. axon hillock: electrically sensitive structure on the cell body of a neuron that integrates signals from multiple neuronal connections.
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.
Detailed explanation-4: -Functions include: clean up brain “debris"; transport nutrients to neurons; hold neurons in place; digest parts of dead neurons; regulate content of extracellular space; promote synaptic connections; clear excess neurotransmitters; ensure the continued function of neurons.
