glio-, gli-, glia-, -glia +
(Greek: glue; in medicine, the network of supporting tissue and fibers that nourishes nerve cells within the brain and spinal cord)
2. Affected with or of the nature of a glioma.
A tumor made up of a gelatinous tissue resembling that found in the umbilical cord.
2. A tumor having the characteristics of glioma and neuroma.
2. Rare mixed tumors of the brain and rarely the spinal cord which contain malignant neuroectodermal (glial) and mesenchymal components, including spindle-shaped fibrosarcoma cells.
These tumors are highly aggressive and present, primarily in adults, as rapidly expanding mass lesions. They may come up in tissue that has been previously irradiated.
2. A process leading to scars in the central nervous system that involves the production of a dense fibrous network of glial cells (supporting cells) in areas of damage.
Gliosis is a prominent feature of many diseases of the central nervous system, including multiple sclerosis and stroke. After a stroke, nerve cells die and are replaced by areas of gliosis
2. The third type of glial cell, along with astrocytes and oligodendrocytes (which together form the macroglia).
Microglia vary in appearance depending on developmental stage, functional state, and anatomical location. Subtype terms include ramified, perivascular, ameboid, resting, and activated.
Microglia clearly are capable of phagocytosis and play an important role in a wide spectrum of neuropathologies.
It has also been suggested that they act in several other roles including in secretion (cytokines and neural growth factors), in immunological processing (antigen presentation), and in central nervous system development and remodeling.
2. The delicate network of branched cells and fibers that supports the tissue of the central nervous system.
3. The supporting or non-neuronal tissue cells of the central and peripheral nervous system.
They perform the less specialized functions of the nerve network.
2. Specialized cells that surround neurones, providing mechanical and physical support and electrical insulation between neurones.
2. A class of neuroglial (macroglial) cells in the central nervous system.
3. Etymology: from Greek, literally meaning, "few tree cells".
The important function of these cells is the formation of insulating myelin sheaths of axons in the central nervous system.
