The cerebral cortex contains the bodies of neurons which appear grey (grey matter). The layer under the cortex contains myelinated axons (white matter).
The connective tissue that covers unmyelinated and myelinated axons is called endoneurium.
myelinated axons
In the central nervous system, neuronal axons are myelinated by oligodendrocytes. In the peripheral nervous system axons are myelinated by Schwann cells.
Large myelinated axons.
The cerebral cortex contains the bodies of neurons which appear grey (grey matter). The layer under the cortex contains myelinated axons (white matter).
In preserved brains, the myelinated axons look white. Therefore, what we call "white matter" is typically made of axons.
Yes White matter is the part of the nervous system that is dense is myelinated axons
The connective tissue that covers unmyelinated and myelinated axons is called endoneurium.
no, most gated mandiable channels are concentrated at the nodes of ranvier of myelinated axons.
the axons of myelinated neurons are embeded in a protective covering of gray matter.
In myelinated axons, the voltage gated sodium ions are located along the nodes of Ranvier, the exposed places between the myelin segments. The gates here, however, are not particularly more concentrated than on other un-myelinated axons. TRUE
nerves
Most axons are covered with a protective sheath of myelin, a substance made of fats and protein, which insulates the axon. Myelinated axons conduct neuronal signals faster than do unmyelinated axons.
White matter in the nervous system is caused when the axons in the area are myelinated. This means that the axons have a fatty protein covering to provide insulation. The myelin sheath is composed of special cells calls Schwann Cells.
myelinated axons
In the central nervous system, neuronal axons are myelinated by oligodendrocytes. In the peripheral nervous system axons are myelinated by Schwann cells.
