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.
Neuroglia are helper cells that provide both structural and metabolic support for the neurons. In the PNS there are schwann cells and satellite cells. In the CNS there are astrocytes, oligocendrocytes, microglia, and ependyma.
the glial cells together with the extracellular tissue.
Supportive or connective structure of the nervous system; also called glia.
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
Greek neuron = nerve, and gloia = glue; hence, the connective tissue of the central nervous system; adjective - neuroglial.

Supporting, non-impulse generating cells of the nervous system (e.g. astrocytes and oligodendrocytes).
General term to describe a group of cells in the CNS that include neuroectoderm derivated cells such as astrocytes, oligodendrocytes, ependyma and mesoderm-derived microglia.
(noo'-ROG-lee-aw) Supportive cells of the nervous system that are most prevalent in the brain and spinal cord.
supporting structure of nervous tissue. Appears to play a role in myelin formation.
The non-neuronal cells of the nervous system. They not only provide physical support, but also respond to injury, regulate the ionic and chemical composition of the extracellular milieu, participate in the BLOOD-BRAIN BARRIER and BLOOD-RETINAL BARRIER, form the myelin insulation of nervous pathways, guide neuronal migration during development, and exchange metabolites with neurons. Neuroglia have high-affinity transmitter uptake systems, voltage-dependent and transmitter-gated ion channels, and can release transmitters, but their role in signaling (as in many other functions) is unclear.
Cells descended from the same epiglastic cells which give origin to the neurons, but which have been developed with the power of reproduction, but no marked irritability. Neuroglia is functionally the connective tissue of the central nervous system; it supports and confines the neurons, the fibers, and the various vessels which nourish these.
Tissue supporting and filling the spaces between the nerve cells of the central nervous system.
Gr. neuron - nerve, Gr. glia - glue]. Cells of the central nervous system which provide support, protection and insulation for neurons.
cells that support and protect neurons.
Neuroglia refers to glial cells or glia cells of the nervous system that support the neurons (nerve cells). They form insulating sheets of tissue around the neurons (called myelin), preventing impulses from traveling between adjacent neurons. Other functions include providing nutrition and controlling the fluids surrounding the neurons.
The supporting cells of the central nervous system.
nervous system cells specialized to perform connective tissue functions; in the CNS, include astrocytes, oligodendrocytes, microglia, & ependyma; in the PNS, include neurolemmocytes (Schwann cells) & ganglion satellite cells; also called glial cells
Non-neuronal cells that provide support and nutrition to neurons. A large class of these in C. elegans are the support cells of the neuronal sensilla. See Glial cell
