Tax deferred investments not only help investors avoid cash outflows for taxes in the immediate future, but they can help investors generate higher returns. That's because the money that would normally be used for tax payments is instead allowed to remain in the account and earn a return.
Glial cell: A supportive cell in the central nervous system. Unlike neurons, glial cells do not conduct electrical impulses.
These glia include the oligodendrocytes, ependymal cells, and astrocytes. In the peripheral nervous system, glia derive from the neural crest. These PNS glia include Schwann cells in nerves and satellite glial cells in ganglia.Current research involving glial cells in the human cochlea proposes that these cells are the common precursor to both mature Schwann cells and satellite glial cells.s the Greek name implies, glia are commonly known as the glue of the nervous system; however, this is not fully accurate. Neuroscience currently identifies four main functions of glial cells: 1  To surround neurons and hold them in place. 2  To supply nutrients and oxygen to neurons.
