Schwann cells
Oligodendrocytes produce myelin in the brain and spinal cord. This process is known as myelination and the myelin will warp itself around the neurons.
Form myelin in the brain and spinal cord....
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.
Schwann cells make the myelin sheath that encloses some axons
Brain & spinal cord neurons are not myelinated
The myelin sheath, an insulating layer around the axon of a neuron, is mainly made up of H20 (40%); the dry mass of myelin is made up of mostly lipids (70 - 80%), and the rest is proteins (30 - 15%). There are three types of myelin protein, one of which is myelin basic protein. The lipid that mostly makes up myelin is called galactocerebroside.
Schwann cells (PNS)
The myelin sheath forms a protective layer over nerves. However, it is not present on all nerves. Retinal nerves for instance normally are devoid of myelin.
The outside of the Dura Mater (a protective layer of the spinal cord and brain) of the spinal cord.
To cushion your brain and spinal cord and provide nutrients for the brain. It is found in the ventricular system, in the brain and spinal cord and the subarachnoid space between the pia mater and the arachnoid mater of the meninges.
Acute disseminated encephalomyelitis (ADE) is a neurological disorder involving inflammation of the brain and spinal cord. A hallmark of the disorder is damage to the myelin sheath that surrounds the nerve fibers in the brain.
