A typical neuron has a myelin sheath insulating its axon. It is formed from cells known as Schwann cells. Some nervous system disorders, such as adrenoleukodystrophy result from the deterioration of the myelin sheath.
Why is the myelin sheath important to the correct functioning of the neuron?
The surface of the myelin sheath carries many receptors for neurotransmitters, allowing the neuron to receive chemical signals
Gaps in the myelin sheath allow for saltatory conduction, where electrical impulses jump from one covered area to another
The myelin sheath blocks external signals that originate outside the neuron, preventing interference with nervous signal transmission
None of these
