The non conducting supporting cells of nervous tissue is  

Explanation

Nervous tissue are two types. 1) Nervous, 2) Supporting cell or neuroglia.
Neuroglia (supporting cells) : These are the supporting and non-conducting cells that provide a micro environment suitable for neuronal activity. Unlike neurons, they continue to divide throughout the life. Neuroglial cells of the CNS include oligodendrocytes (that form myelin sheath as mentioned above), astrocytes (star shaped cells) that form interconnected network and bind neurons and capillariés (helping in providing blood-brain barrier), ependymal cells, which are ciliated cells that line the cavities of brain and spinal cord to bring movements in the cerebrospinal fluid, microglial cells, which are phagocytic cells, of mesodermal origin. Neuroglial cells of the peripheral nervous system include the satellite cells and Schwann cells. Satellite cells surround the cell bodies in ganglia, and Schwann cells form neurolemma around axons.
