Myelin sheath insulates axons for speedier signaling
myelin
The layer of lipid around an axon is called myelin sheath. It acts as an insulator, allowing for faster transmission of nerve impulses along the axon.
The fatty tissue that covers axons and speeds up impulses is called myelin. Myelin acts as an insulating layer, which helps to increase the speed and efficiency of nerve impulse transmission along the axon.
The myelin sheath. Due to its insulating properties, the myelin sheath prevents the movement of ions in nerve cells. Therefore nervous impulses will jump between the gaps in the myelin sheath (called the Nodes of Ranvier). This is a lot quicker than the conduction in non-myelinated nerve fibres which occurs by the movement of ions across each of the nerve cell membranes.
Gaps in the myelin sheath can result in reduced conduction velocity of nerve impulses, leading to impaired communication between neurons. This can manifest as symptoms such as weakness, numbness, and coordination issues. Conditions like multiple sclerosis can cause damage to the myelin sheath, resulting in these gaps.
myelin
if neurons didn't have myelin sheath then the transmission of nerve impulses is slowed or stopped
Myelin sheath never transmits the impulse from one neuron to another. On the contrary these are insulating cells which prevent transmission of nerve impulses.

The layer of lipid around an axon is called myelin sheath. It acts as an insulator, allowing for faster transmission of nerve impulses along the axon.
Neural impulses (action potentials) are transmitted through axons which are covered in a myelin sheath for insulation.
Myelin sheath. It is a fatty layer that surrounds the axon of a neuron and helps to speed up the transmission of electrical impulses along the neuron.
Neurons are covered by a myelin sheath, which consists of layers of fatty tissue that insulates the axon and reduces leakage of impulses. The myelin sheath is formed by specialized cells called oligodendrocytes in the central nervous system, and Schwann cells in the peripheral nervous system. This insulation allows for faster and more efficient transmission of electrical impulses along the axon.

The myelin sheath that surrounds the nerve
Myelin sheath is the "cover" if you like of nerves. It's structure is important in helping pass the nerve impulses along it's axon, from the body, to the terminal buttons. Long story short, a degeneration of the Myelin sheath leads to interrupted, or non existent impulses, and causes a very well known disease, called MS (multiple sclerosis)
insulating layer called myelin sheath. This myelin sheath helps to speed up the conduction of electrical impulses along the axon by allowing the impulse to jump between nodes of Ranvier, known as saltatory conduction.
