Does myelin sheath transmits impulses from one nuron to another?

Myelin sheath never transmits the impulse from one neuron to another. On the contrary these are insulating cells which prevent transmission of nerve impulses.

Which structure if the neuron transmits an impulse through the myelin sheath?
Neural impulses (action potentials) are transmitted through axons which are covered in a myelin sheath for insulation.
What would happen if the neuron did not have a myelin sheath?
if neurons didn't have myelin sheath then the transmission of nerve impulses is slowed or stopped
How does the myelin sheath and synapse affect nerve impulses speed up or slow down?
Myelin sheath insulates axons for speedier signaling
Neural impulses speed increases when the axon is encased by what?
Myelin Sheath
What is the fatty tissue that covers axons and speeds up impulses as they travel from cell to cell?
That substance is called the myelin cell or myelin sheath.
State the structure of neurons which reduces leakage of impulses?
Myelin sheath, which is only found on long axons (white matter), not on short cortical neurons (grey matter).
What is the insulating layer wrapped around nerve cells that increases the speed of nerve impulse transmission?
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.
How is the structure of the myelin sheath related to its function?
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)
What is the fatty materiel that covers the axon and helps with nerve impulses?
It is called as myelin sheath. It acts as an insulator of the electrical wire. It is made up of cells.
What purpose does the myelin covering an axon serve?
insulating sheath that speeds up the transmission of impulses along an axon
What increases the speed of the transmission?
Myelin Sheath Myelin Sheath
What is the chemical substance that transmits nerve impulses across a synapse?
Melination The myelin sheath means that the action potential can occur in between the schwann cells. Myelinated meurones conduct much quicker that non-myleinated neurones, even at speeds upto 120m/s
