Glial cells (also known as neuroglia) provide support to the neural tissue, regulate the environment around the neurons, and protect against foreign invaders.    From Wordnik.com.  [Neurotoxicity] Reference

The nervous tissues are composed of nerve cells and their various processes, together with a supporting tissue called neuroglia, which, however, is found only in the brain and medulla spinalis.    From Wordnik.com.  [IX. Neurology. 1. Structure of the Nervous System] Reference

These cells make up part of the neuroglia (nyoo-rog'lee-uh; "nerve-glue" G) that surrounds and supports the nerve cells themselves.    From Wordnik.com.  [The Human Brain]

If these theories be true, what, it may be asked, is the agency that causes the dendrites to contract or the neuroglia cells to expand?.    From Wordnik.com.  [Scientific American Supplement, No. 1178, June 25, 1898] Reference

Cajal, on the other hand, believes that the neuroglia cells are contractile, and may expand so as to interpose their branches as insulating material between the synapses formed by the dendrites of the nerve cells.    From Wordnik.com.  [Scientific American Supplement, No. 1178, June 25, 1898] Reference

The "white matter" of the central system consists chiefly of axons with their enveloping or medullary, sheath and neuroglia.    From Wordnik.com.  [The Mind and Its Education] Reference

A part of the mass of gray matter also consists of the neuroglia which surrounds the nerve cells and fibers, and a network of blood vessels.    From Wordnik.com.  [The Mind and Its Education] Reference

In man the original cavity is filled up by neuroglia and its wall becomes thickened, but much more so on its ventral than on its dorsal aspect.    From Wordnik.com.  [IX. Neurology. 4c. The Fore-brain or Prosencephalon] Reference

These mesothelial cells continue inward only a short distance, neuroglia cells probably replacing on the outer surface the mesothelial elements.    From Wordnik.com.  [IX. Neurology. 4h. The Cerebrospinal Fluid] Reference

The walls of the vesicles are developed into the nervous tissue and neuroglia of the brain, and their cavities are modified to form its ventricles.    From Wordnik.com.  [I. Embryology. 6. The Neural Groove and Tube] Reference

In addition to these are other fibers, which have a vertical direction, and are the processes of large neuroglia cells, situated in the nuclear layer.    From Wordnik.com.  [IX. Neurology. 4a. The Hind-brain or Rhombencephalon] Reference

Thus, neuroglia is evidently a connective tissue in function but is not so in development; it is ectodermal in origin, whereas all connective tissues are mesodermal.    From Wordnik.com.  [IX. Neurology. 1. Structure of the Nervous System] Reference

The apex is capped by a V-shaped or crescentic mass of translucent, gelatinous neuroglia, termed the substantia gelatinosa of Rolando, which contains both neuroglia cells, and small nerve cells.    From Wordnik.com.  [IX. Neurology. 3. The Spinal Cord or Medulla Spinalis] Reference

This gelatinous substance consists mainly of neuroglia, but contains a few nerve cells and fibers; it is traversed by processes from the deep ends of the columnar ciliated cells which line the central canal (Fig. 667).    From Wordnik.com.  [IX. Neurology. 3. The Spinal Cord or Medulla Spinalis] Reference

It consists of neuroglia cells and fibers and is invaded by columns which grow into it from the pars intermedia; imbedded in it are large quantities of a colloid substance histologically similar to that found in the thyroid gland.    From Wordnik.com.  [XI.

Some of the cells are stellate in shape, with ill-defined cell body, and their fine processes become neuroglia fibers, which extend radially and unbranched (Fig. 623, B) among the nerve cells and fibers which they aid in supporting.    From Wordnik.com.  [IX.

It is covered by a thin layer of gray substance continuous with that of the medulla spinalis; superficial to this is a thin lamina of neuroglia which constitutes the ependyma of the ventricle and supports a layer of ciliated epithelium.    From Wordnik.com.  [IX.

Even in the gray matter, though sometimes thickly distributed, the ganglion cells are never in actual contact one with another; they always lie embedded in intercellular tissues, which came to be known, following Virchow, as the neuroglia.    From Wordnik.com.  [A History of Science: in Five Volumes.

In the perivascular spaces, the pia apparently enters as a mesothelial lining of the outer surface of the space; a variable distance from the exterior these cells become unrecognizable and are apparently lacking, replaced by neuroglia elements.    From Wordnik.com.  [IX.

—This lies next the central core of neuroglia, and its fibers consist of the axons or afferent processes of the mitral cells passing to the brain; some efferent fibers are, however, also present, and end in the molecular layer, but nothing is known as to their exact origin.    From Wordnik.com.  [IX.

The mantle layer represents the whole of the future gray columns of the medulla spinalis; in it the cells are differentiated into two sets, viz., (a) spongioblasts or young neuroglia cells, and (b) germinal cells, which are the parents of the neuroblasts or young nerve cells (Fig. 641).    From Wordnik.com.  [IX.

"And what could we reply to the naturalist if, before he could agree to the assumption of a World-soul he required that we should show him -- bedded in neuroglia and nourished by warm arterial blood -- anywhere in the world a convolution of ganglionic centres co-extensive with the psychic capacity of such a Soul" (!).    From Wordnik.com.  [Freie wissenschaft und freie lehr.

The anterior end of the neural tube becomes expanded to form the three primary brain-vesicles; the cavity of the tube is subsequently modified to form the ventricular cavities of the brain, and the central canal of the medulla spinalis; from the wall the nervous elements and the neuroglia of the brain and medulla spinalis are developed.    From Wordnik.com.  [IX. Neurology. 2. Development of the Nervous System] Reference

The primary elements in the tissue of the nervous system are three; nerve fibres, which are simply conducting threads, telegraph wires; ganglion cells, which are the officials of the system; and neuroglia, a fine variety of connective tissue which holds these other elements together, and may also possibly exercise a function in affecting impressions.    From Wordnik.com.  [Text Book of Biology, Part 1: Vertebrata] Reference
