neuroglia

True, the neurones are held in place, and perhaps insulated, by a kind of soft cement called neuroglia.

The "white matter" of the central system consists chiefly of axons with their enveloping or medullary, sheath and neuroglia.

The neuroglia theory explains this very well and does away with the difficulty.

This may be applied to the neuroglia cells apparently as well as to the muscle fibers.

He has also described particularly a special form of neuroglia cells which lie close to the blood vessels.
