What are the gaps found along along a myelin sheath?
The gaps found along a myelin sheath are called nodes of Ranvier. These gaps allow for the rapid conduction of nerve impulses by allowing the action potential to jump from one node to the next, a process known as saltatory conduction.
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.
What does myelin sheath wrap around?
The myelin sheath wraps around the axons of neurons in the nervous system. This fatty layer helps to insulate and protect the axon, allowing for faster transmission of electrical signals along the neuron.
What are specialized coverings of the axon?
Specialized coverings of the axon include the myelin sheath, which is formed by oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. The myelin sheath acts as an insulating layer that speeds up the conduction of nerve impulses along the axon. Nodes of Ranvier are gaps in the myelin sheath where action potentials are regenerated, allowing for saltatory conduction.
What insulates nerve fibers?
Myelin insulation insulates nerve fibers by wrapping around them and forming a protective sheath. This myelin sheath helps to increase the speed of nerve impulse conduction along the nerve fibers.
Where are nodes of ranvier found?
In the fatty myelin sheath there are gaps between the axons. The myelin sheath gaps are referred to as the nodes of Ranvier.

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.
