glial cells Nonconducting cells that serve as support cells in the nervous system and help to protect neurons.
glomerulus A tangle of capillaries that makes up part of the nephron; the site of ?ltration.
[edit] Glial cells
Main article: Glial cell
Glial cells are non-neuronal cells that provide support and nutrition, maintain homeostasis, form myelin, and participate in signal transmission in the nervous system.
glial cells Supportive cells that are closely associated with neurons.

Glia
Glial cells surround neurons. Once thought to be simply support for neurons (glia = glue), they turn out to serve several important functions.
There are three types: ...
So for example glial cells, which are one of the lineage choices for a stem cell, in and of itself can tell a stem cell to become a neuron. So when the stem cell's dividing in proximity to certain types of glial cells, they then become neurons.
There are stem cells in neural tissue that give rise to neurons and astroglial cells and things like that. And muscle has stem cells. And there are many different kinds of stem cells that have been identified in adults.
Some axons are wrapped in a myelin sheath formed from the plasma membranes of specialized glial cells known as Schwann cells. Schwann cells serve as supportive, nutritive, and service facilities for neurons.
A regulatory system of the body that consists of neurons and neuroglial cells. The nervous system is divided into two parts, the central nervous system (CNS) and the peripheral nervous system (PNS).

The small gaps in the myelin sheath between successive glial cells along the axon of a neuron; also, the site of high concentration of voltage-gated ion channels.

Intermediate filaments found in neurons and glial cells include peripherin, neurofilaments, and glial fibrillary acidic protein (GFAP).
