Detailed explanation-1: -The actual nerve cell is the neuron. It is the “conducting” cell that transmits impulses and the structural unit of the nervous system. The other type of cell is neuroglia, or glial, cell. The word “neuroglia” means “nerve glue.” These cells are nonconductive and provide a support system for the neurons.
Detailed explanation-2: -Nervous tissue contains two major cell types, neurons and glial cells. Neurons are the cells responsible for communication through electrical signals. Glial cells are supporting cells, maintaining the environment around the neurons.
Detailed explanation-3: -Nervous tissue is composed of neurons and supporting cells called neuroglia, or ‘’ glial cells.” There are six types of neuroglia. Four are found in the central nervous system, while two are found in the peripheral nervous system.
