What is the gap called that separates the myelin sheaths?
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.
What is the myelin sheath's function?
The function of the myelin sheath is to insulate the axon of the neuron. When there are gaps in the sheath, known as nodes of Ranvier, the nerve impulse can jump from gap to gap, thus increasing greatly the speed of conduction of the nerve impulse. This is known as saltatory conduction.

What insulates nerve fibers?
Myelin sheaths insulate nerve fibers
The neurolemma and the myelin of the myelinated axons are interrupted at regular intervals along the axon by?
The gap between each myelinated section of an axon is known the node of ranvier.
What is the white lipid material that insulates the axon of a neuron?
The white lipid material that insulates the axon of a neuron is called myelin. In the central nervous system, myelin is created by oligodendrocytes while in the peripheral nervous system the myelin is created by Schwann cells. The purpose of myelin is to speed up action potentials. It's important to know that the myelin does not coat the axon entirely; each sheath of myelin is separated by a gap, called a node of Ranvier. These gaps are responsible for the quick transport of action potentials, due to the fact that the potentials can "jump" from node to node rather than having to travel down the entire length of the axon (this is called saltatory conduction).
What is the definition of myelin sheath?
A myelin sheath is a layer of myelin (a dielectric, or electric insulator) around the axon of a neuron.
It insulates the axon of the neuron?
An insulating layer that surrounds the axon is a myelin sheath.

How does nicotine affect the myelin production?
Nicotine stimulates CREB phosphorylation which regulates the expression of myelin basic protein and myelin oligodendrocyte glycoprotein.
