When the nerve impulse encounters a myelin-covered section of neuron?
When the nerve impulse encounters a myelin-covered section of a neuron, it jumps between the nodes of Ranvier, allowing for faster transmission speed due to saltatory conduction. Myelin acts as an insulator, preventing the impulse from dissipating and increasing the efficiency of signal transmission along the neuron.
What would happen to a nerve impulse carried by an interneuron if the tips of the interneorons axon were damaged?
If the tips of an interneuron's axon were damaged, the transmission of the nerve impulse would likely be disrupted or slowed down. This could result in problems with signal conduction between neurons, leading to impaired communication within the nervous system.
What part of the nerve cell-helps to speed up conduction?
The part of the nerve cell that helps to speed up conduction is the myelin sheath. This insulating layer surrounds the axon and allows electrical impulses to travel more quickly by facilitating saltatory conduction, where the impulse jumps between nodes of Ranvier. This increases the efficiency and speed of signal transmission along the nerve cell.
What minerals are needed for muscle contraction and conduction of nerve impulses?
Minerals such as calcium, magnesium, sodium, and potassium are essential for muscle contraction and nerve impulse conduction. Calcium is particularly important for initiating muscle contractions and transmitting nerve impulses, while magnesium, sodium, and potassium help regulate muscle relaxation and contraction as well as nerve impulse transmission.
Functional connection between two neurons is a?
functional connection between two neurons is the transmission of electrical signals from one neuron to another through a synapse. When an electrical impulse reaches the axon terminal of the pre-synaptic neuron, it triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the post-synaptic neuron, allowing the electrical signal to be transmitted and continue the communication between neurons.
What is the difference between synaptic and nerve impulse transmission?
Synaptic transmission is chemical, while nerve impulse or axonal transmission is electrical.
What is the difference in transmission between myelinated and unmyelinated fibers?
Impulse transmission on an unmyelinated nerve fiber is much slower than the impulse transmission on a myelinated nerve fiber.
Does the saltatory conduction reduce the energy expenditure of the sodium potassium pump for impulse transmission?
yes
Which structure is coated with myelin to increase speed of nerve impulse transmission?
The structure coated with myelin to increase the speed of nerve impulse transmission is the axon. Myelin is a fatty substance that forms a protective sheath around the axon, facilitating faster electrical signal conduction through a process called saltatory conduction. This allows the nerve impulses to jump between the gaps in the myelin sheath, known as nodes of Ranvier, significantly enhancing transmission speed.

When the nerve impulse encounters a myelin-covered section of a neuron, it jumps between the nodes of Ranvier, allowing for faster transmission speed due to saltatory conduction. Myelin acts as an insulator, preventing the impulse from dissipating and increasing the efficiency of signal transmission along the neuron.
What impulse conduction is the fastest in neurons?
Axons conduct the nerve impulses. Dendrites receive the impulses. Possible the impulses go through the dendrites faster, though the synaptic cleft may slow this pathway. Dendrites are much shorter than axons.
What is impulse conduction?
Party of nervous
How do you tell the difference between a rat impulse paintball markers?
the Rat Impulse LTD has: a regulator, The regular Rat Impulse does not.
What is impulse conduction is fastest in neurons?
Impulses that travel along myelinated neurons are the fastest.
What refers to the constiction or gaps that occurs between the Schwann cells that are for impulse conduction in myelinated fibers?
Nodes of Ranvier
