Oligodendrocyte; processes of the oligodendrocytes form the myelin sheaths around the CNS nerve fibers
No, myelin sheaths actually speed up nerve impulses by increasing the speed of signal transmission along the nerve fibers. This is due to the insulation effect of myelin, which helps to prevent signal loss or leakage.
The main function of glial cells, specifically oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system, is to provide insulation to neurons through the formation of myelin sheaths. These myelin sheaths wrap around the axons of neurons, which helps to increase the speed and efficiency of electrical signal conduction along the neuron.
The autoimmune disease that results in the destruction of myelin sheaths is called multiple sclerosis (MS). This condition leads to disruption in the transmission of signals along the nerves, causing a range of symptoms including weakness, numbness, vision problems, and difficulties with coordination and balance.
The Schwann cells in the peripheral nervous system (PNS) help to form myelin sheaths around larger nerve fibers. These cells wrap around the nerve fibers to provide insulation and support for faster nerve impulse conduction.
Myelin sheaths are located around the nerve cells. In central as well as peripheral nervous system.
Your question is not complete. There is not enough information. What are you referring to as "they". Some nerve fibers have thick myelin sheaths and some don't.
The gap between myelin sheaths is called the node of Ranvier. These nodes are important for enhancing the speed of nerve impulse transmission along the axon by allowing action potentials to "jump" between them in a process known as saltatory conduction.
By myelin sheath.
In a typical neuron, sheaths of fatty tissue are called the Myelin sheath. The myelin sheath surrounds parts of the axon of a nerve cell which speeds up neurotransmitters.

myelin sheaths
No, they form myelin sheaths on axons in the CNS while schwann cells form myelin sheaths in the PNS. Hope this answers your question.

MS
No. It does not. It can not. It neither affect the neurons also.
Schwann cells in the peripheral nervous system form myelin sheaths around axons, which helps to speed up the transmission of nerve impulses. These myelin sheaths act as insulating layers that ensure efficient communication between neurons.
