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.
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.

The Schwann cell forms a myelin sheath around the?
axons of neurons in the peripheral nervous system. The myelin sheath helps to insulate the axon and improve the speed of electrical signal conduction along the neuron. Schwann cells are also involved in nerve regeneration and support neuron function within the peripheral nervous system.
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.
In a typical neuron sheaths of fatty tissue are called?
In a typical neuron, the sheaths of fatty tissue that surround and insulate the axon are called myelin sheaths. These sheaths help to speed up the transmission of electrical impulses along the axon.
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 cell produces the myelin in peripheral nerves?
Schwann cells produce myelin in peripheral nerves. Schwann cells wrap around the axon of a neuron to form the myelin sheath, which helps to insulate and speed up the conduction of nerve impulses.
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.
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.
It insulates the axon of the neuron?
The myelin sheath insulates the axon of a neuron, allowing for faster transmission of electrical signals. This fatty layer helps to speed up the signal conduction by allowing the electrical impulse to jump from one node of Ranvier to the next, a process known as saltatory conduction.
What keeps the neuron in working order and has specialized extensions that arise from it?
Myelin sheath
