What else can I help you with?
Gray matter in the spinal cord is mostly?
unmyelinated axons.
Does myelinated axons of the cns make up the white matter of the brain and spinal cord?
Yes, myelinated axons in the central nervous system (CNS) constitute the white matter of the brain and spinal cord. The myelin sheath, which is a fatty substance, surrounds these axons and increases the speed of nerve signal transmission. In contrast, the gray matter primarily consists of neuronal cell bodies, dendrites, and unmyelinated axons. Thus, the distinction between white and gray matter is largely based on the presence of myelinated versus unmyelinated axons.
White matter of the spinal cord?
it is the substance surrounding the gray matter. It is also composed of myelinated nerve fibers and makes up nerve pathways called tracts.
What is the portion of the spinal cord made up of cell bodies and unmyelinated axons?
Gray matter
What spinal cord location would you find the origin of the white rami communicantes.?
The white rami communicantes are myelinated pre-ganglionic fibers (myelinated axons) from cell bodies located in the internal gray of the spinal cord. These fibers represent general visceral efferents of the sympathetic nervous system.
Is white matter dense in myelinated axons?
Yes, white matter is dense in myelinated axons. White matter in the brain and spinal cord is primarily composed of nerve fibers that are encased in myelin sheaths, which give it its white color. Myelination helps to speed up the transmission of nerve impulses along these axons.
Area of spinal cord that contains nerve fibers surrounded by myelin sheath?
the part of the spinal cord that contains mylinated axons is the White matter portion.
What forms the white matter in the spinal cord?
myelinated axons the grey matter are the cell bodies . . . which is logical when you think about it the axons need to be on the outside of the spinal cord so they can extend to all the other parts of the body to carry sensory information.
What contains myelinated axons?
Myelinated axons are found in the central nervous system (CNS) within areas such as the brain and spinal cord, as well as in the peripheral nervous system (PNS) within nerves outside the CNS. Myelin, a fatty substance produced by glial cells like oligodendrocytes in the CNS and Schwann cells in the PNS, wraps around these axons to insulate and speed up the transmission of nerve impulses.
Are nerve fibers in ascending tracts myelinated?
If I was paying attention in med school, I think... The pre-ganglionic fibers are myelinated and the post-ganglionic are unmyelinated. This is in reference to the sympathetic and parasympathetic systems.
Where are the Axons located in the spinal cord?
On the outer parts
What is the white matter of the spinal cord contain?
axons
