A nerve cell with a myelin sheath.
The sheath acts as an insulator of electrical conduction which is how the nerve cell conducts action potential. It conducts faster because the insulator prevents flow of ions right beside the channels that are being activated. So it 'skips' distance.

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 a group of neurons with little to no myelin is known as?
read your text book
What cell main function is to provide insulation and structure for neurons?
myelin sheath
What structure insulates neurons?
Myelin Sheath is the structure that insulates most part of neuron
Do some neurons lack an axon and communicate only with adjacent neurons?
If they are neurons they have an axon, some cell types do communicate using gap-junctions. Yes, some complex sensory organs ( in the retina and organ of Corti for example) do not have axons. These cells liberate transmitter from their soma directly onto postsynaptic neurons in proportion to the membrane potential change they experience.
Do action potential transmission is faster in myelinated neurons?
TRUE. Neurons with myelin (or myelinated neurons) conduct impulses much faster than those without myelin.
What is the fatty substance that speeds up transmission of impulses and surrounds the axon of a neuron?
The fatty tissue surrounding the axon of a neuron is called myelin.
Neurons can conduct messages faster if they have?
A myelin sheath.
How is myelin formed within the central nervous system?
The glial cells that surround the neurons produce myelin.
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 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
What is a group of neurons with little to no myelin is known as?
read your text book
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.
Does a nervous breakdown affect the myelin sheaths?
No. It does not. It can not. It neither affect the neurons also.
What cell main function is to provide insulation and structure for neurons?
myelin sheath
What neurological disease gradually destroys the myelin sheaths of neurons in the CNS?
Multiple Sclerosis
Where is the axon not insulated with myelin?
Brain & spinal cord neurons are not myelinated
