  • n. The supportive tissue of the nervous system, including the network of branched cells in the central nervous system (astrocytes, microglia, and oligodendrocytes) and the supporting cells of the peripheral nervous system (neurilemma and satellite cells). Also called glia.

  • n. glial cell

from the GNU version of the Collaborative International Dictionary of English

  • n. The delicate connective tissue framework which supports the nervous matter and blood vessels of the brain and spinal cord; called also Kölliker's reticulum. It is composed of cells which are not neurons. Once thought to serve merely a supporting funciton, they are now believed to have important metablolic functions. Among them are the astrocytes, ependymal cells, oligodendroglia cells, and microglia cells.

from The Century Dictionary and Cyclopedia

  • n. The peculiar sustentacular tissue of the cerebrospinal axis.

  • n. sustentacular tissue that surrounds and supports neurons in the central nervous system; glial and neural cells together compose the tissue of the central nervous system

neuro- +‎ glia


  • Glial cells (also known as neuroglia) provide support to the neural tissue, regulate the environment around the neurons, and protect against foreign invaders.


  • 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.

  • Immunity, neuroglia and neuroinflammation in autism.

    The Autoimmune Epidemic

  • Note: The first use of the word “neuroglia” is on p.

    The Other Brain

  • There are two types of nervous tissue — neurons and neuroglia.


  • The brain has ganglia and nerve fibers, has neuroglia and vessels, has different colors (is colored this way or that) and so on.

    Neutral Monism

  • These cells make up part of the neuroglia (nyoo-rog'lee-uh; "nerve-glue" G) that surrounds and supports the nerve cells themselves.

    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?

    Scientific American Supplement, No. 1178, June 25, 1898

  • 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.

    Scientific American Supplement, No. 1178, June 25, 1898

  • 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.
