What produce myelin in the brain and spinal cord?
Oligodendrocytes produce myelin in the brain and spinal cord. This process is known as myelination and the myelin will warp itself around the neurons.
What does the white matter in the brain do?
No, the white matter in brain tissue is the area of brain tissue that contains the nerve fibre tracts with their covering of myelin which appears white.
Function of oligodendrocytes?
Form myelin in the brain and spinal cord....
Cells that produce myelin for cells outside the brain and spinal cord are the?
Schwann cells
Which cells produce myelin for cells outside the brain and spinal cord?
schwann cells
Where is the axon not insulated with myelin?
Brain & spinal cord neurons are not myelinated
Area of cns that has no myelinated nerve fibers?
The grey matter of the brain. Myelin is the insulation (like rubber around a copper wire) to help transmit electrical pulses. The white matter of the brain, our spinal cord and peripheral nerves all transmit signals wit the help of myelin. The grey matter is where the thoughts or actions originate and mostly consist of cell bodies.
Where does the spinal cord have gray matter?
The grey matter on a spinal cord is on the spinal roots.
Where are the grey and white matter located in the brain?
To oversimplify it significantly with an analogy, the grey matter is data processing neurons and the white matter is the myelin insulated cabling axons of those neurons that interconnects them to exchange data. Myelin is fatty, giving the white color to the white matter.
Do neurotransmitters form the myelin sheath?
No, neurotransmitters do not form the myelin sheath. Myelin is formed by specialized types of glial cells called oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. Neurotransmitters are chemicals that are released by neurons to transmit signals across synapses.
Is the myelin sheath white?
Yes. You are right. White matter of brain is mainly composed of myelin sheaths, which surround the axons and gray matter is composed of nerve cell bodies.
What is neuroglial cells that form the fatty myelin sheath on the neurons of the brain and spinal cord called?
Schwann cells (PNS)
