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 are gaps in myelin sheath that allow nerve impulses to quickly move down the axon by jumping from section to section?
The gaps in the myelin sheath are called Nodes of Ranvier. These nodes are crucial for a process known as saltatory conduction, where nerve impulses jump from one node to the next, significantly increasing the speed of transmission along the axon. This jumping occurs because the myelin sheath insulates the axon, allowing the electrical signal to travel more efficiently. As a result, the presence of these nodes enhances the overall speed and efficiency of neural communication.
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 are there spaces between leaves?
The spaces between leaves, known as leaf gaps, occur due to the arrangement of leaves on a plant's stem, allowing for optimal light capture and air circulation. This spacing helps reduce competition for sunlight and minimizes shading of lower leaves. Additionally, the gaps can facilitate pollination and seed dispersal by providing access to insects and other animals. Overall, these spaces contribute to the plant's overall health and efficiency in photosynthesis.
What are the gaps called where the axon membrane is exposed?
Nodes of Ranvier

Which structure of a neuron increases the speed of impulse transmission?
The structure of a neuron that increases the speed of impulse transmission is the myelin sheath. This fatty insulating layer surrounds the axon and allows electrical impulses to jump between the nodes of Ranvier, which are gaps in the myelin. This process, known as saltatory conduction, significantly enhances the speed of signal transmission along the axon.
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:
Where are action potentials regenerated as they propagate along a myelinated axon?
First at the axon hillock where the neural impulse is initially triggered, and then at the nodes of Ranvier as the impulse continues to travel along the axon.(Note that the impulse travels as electrotonic conduction between the nodes of Ranvier, underneath the glial cells which myelinate the axon.)
What speeds up nervous impulses?
Nervous impulses are sped up primarily by the myelin sheath, a fatty insulating layer that surrounds the axons of many neurons. This myelination allows impulses to jump between gaps in the sheath, known as nodes of Ranvier, through a process called saltatory conduction. Additionally, the diameter of the axon plays a role, as larger diameters can conduct impulses more quickly due to reduced resistance. Overall, both myelination and axon diameter are key factors in increasing the speed of nerve transmission.

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.
