Gray matter in the spinal cord is mostly?
unmyelinated axons.
What can be defined as billions of neuroglial nerve cell bodies and unmyelinated axons?
gray matter
What makes the matter gray?
Grey matter is nerve tissue that primarily consists of nerve cell bodies, dendrites, and unmyelinated axons, thus having a gray appearance.
What is the portion of the spinal cord made up of cell bodies and unmyelinated axons?
Gray matter
Does Gray matter contain collections of unmyelinated fibers and cell bodies in the central nervous system?
True
What does gray matter in the cortex consist of?
cell bodies and unmyelinated fibers
What is a word for nerve cell bodies outside CNS?
ganglia is a group of cell bodies in the PNS.
What color are masses of myelinated nerve fibers?
Mylein is Fat, and is white. Answer #2 Myelin is actually a cell covering the "shaft" of a nerve axon, improving conduction across the cell as a whole. It doesn't hold stain as well, and generally appears whiter than unmyelinated cells, so they are white. Myelin isn't fat.
Does grey matter contain myelin?
That is a very good question. Gray matter is composed of cell bodies of neurons. Such cell bodies are also covered by myalin sheath. But the colour of myalin sheath is dominated by the color of nerve cell bodies. ( Without the myelin sheath, there will be short circuit.)
What is the color of nerve cell?
nerve cell can be of many colours like green,white,brown.
Which cell process are not myelinated?
According to McGraw Hill (please see related link below): Many nerve fibers in the CNS and PNS are unmyelinated. In the PNS, however, even the unmyelinated fibers are enveloped in Schwann cells. In this case, one Schwann cell harbors from 1 -12 small nerve fibers in grooves in its surface. The Schwann cell's plasma membrane does not spiral repeatedly around the fiber as it does in a myelin sheath, but folds once around each fiber and somewhat overlaps itself along the edges. This wrapping is the neurilemma (also called a mesaxon in unmyelinated nerve fibers). Also, gray matter of the brain and dendrites are unmyelinated, while axons are myelinated.
Collection of nerve cell bodies found outside CNS?
In the peripheral nervous system, which is outside the central nervous system (CNS), collections of nerve cell bodies are called ganglia.
