The single long axon is surrounded by myelin sheath, which is a fatty substance produced by Schwann cells in the peripheral nervous system. The gaps along the axon are called nodes of Ranvier, where the axon is exposed and allows for faster nerve impulse transmission known as saltatory conduction.

Where are the nodes of a neuron located?
Between myelin segments surrounding the axon The axon of a neuron is the single long fibre which caries impulses away from the cell body. It is surrounded by a fatty layer, the myelin sheath, produced by Schwann cells arranged along the length of the axon. The gaps between the myelin sheath cells are called nodes of Ranvier. See http://en.wikipedia.org/wiki/Axon for more information and a diagram. easy answer between the myelin segments surrounding the axon b. between myelin segments surrounding the axon
What two characteristics are highly developed to allow the neuron to perform this function of conducting the Action Potential?
I think your talking about the myelin sheath around the axon and also the nodes of ranvier which are basically gaps in the insulating myelin. These gaps allow the action potential to jump from uncovered spot to uncovered spot rather than traveling the full length of the axon which greatly speeds up reaction time.
Where is the synaptic gap located?
The synaptic gap isn't a region of the brain itself, but a term used to describe the tiny space between an axon terminal and the axon or tissue it is communicating with; so synaptic gaps are spread right throughout both the central and peripheral nervous systems.
Why do myelin covered neurons carry an action potential faster than an uncovered neuron?
Myelin acts as an insulating layer that speeds up the transmission of the action potential by allowing it to "leap" between the nodes of Ranvier. This is called saltatory conduction and helps the action potential travel faster along the axon. With the myelin sheath, the action potential can effectively "jump" from node to node, reducing the time and energy needed for propagation.
How is Clint rock formed?
Clints are formed by chemical weathering. This leaves gaps in the limestone, and slabs of rock outside them, which are called clints.
What are the gaps called where the axon membrane is exposed?
Nodes of Ranvier

What are the gaps between the myelin sheath along an axon?
Node of Ranvier
Where is the axon not insulated with myelin?
The axon is not insulated with myelin at the nodes of Ranvier. These are small gaps along the axon where the myelin sheath is absent and allow for faster propagation of action potentials by saltatory conduction.
What is the fatty substance that speeds up transmission of impulses and surrounds the axon of a neuron?
The fatty substance that surrounds the axon of a neuron and speeds up the transmission of impulses is called myelin. Myelin acts as an insulating layer that helps to maintain the electrical signal within the neuron, allowing for faster and more efficient communication between cells.
What are the gaps in the myelin sheath that create non-insulated areas along an axon?
nodes (:I do not disagree with that answer, but I just want to point out that the nodes have a special name. They are called Nodes of Ranvier, named after the man that discovered them (so Ranvier is capitalized). C:
Can maps be wrong?
Yes, the earth is round, and you cant make a sphere flat. It leaves gaps, so map makers have to improvise and fill in the gaps.

Where are action potentials regenerated as they propagate along a myelinated axon?
Action potentials are regenerated at the nodes of Ranvier along a myelinated axon. The nodes of Ranvier are gaps in the myelin sheath that contain a high concentration of voltage-gated ion channels, allowing for the regeneration of the action potential as it travels along the axon.
Where do ladybirds sleep?
Ladybirds sleep underneath fallen leaves and gaps in trees.
What is tesalation?
Tessellation: to form or arrange patterns of shapes in a layout that leaves no gaps or overlays. So basically, its a series of shapes that are put together leaving no gaps or any overlaps. for example, lots of squares put together would leave no gaps but a circle wouldn't work because if you put them together they leave gaps.
The material surrounding the axon that increases the speed of the nerve impulse is?
The material surrounding the axon that increases the speed of the nerve impulse is the myelin sheath. It is made of fatty substances and acts as an insulator, allowing for faster conduction of the electrical signal along the axon. Nodes of Ranvier are the gaps in the myelin sheath where the signal jumps between to speed up transmission.
