How fast does an action potential travel down a myelinated nerve?
An action potential is not passively propagated down the axon. There have to be ion channels along the axon or else the action potential will gradually decay. So the the rate of that the action potential 'travels' is dependent on the passive property called the length constant of the axon (factor in capacitance, axon diameter) plus the density of ion channels.
Effects of myelination and nodes of ranvier on action potenital conduction?
The velocity of propagation of an action potential depends on axoplasm resistance and membrane resistance. Axoplasm resistance explains how fast a charge can move within an axon. The larger the diameter of the axon, the more quickly it can pass through. Membrane resistance describes how permeable the membrane is to the ion. The less permeable, the faster the propagation of the action potential. Therefore, myelination increases the membrane resistance and ultimately allows for fast propagation. In demyelinating diseases, there is little or sometimes no myelin covering the axons. In these cases action potentials will slow down or completely cease.
What structure in the neuron helps to speed up the transmission of the action potential?
The myelin sheath, which is made of fatty tissue wrapped around the axon, helps to speed up the transmission of the action potential by insulating the axon and allowing the action potential to jump between the nodes of Ranvier. This process is known as saltatory conduction and helps to increase the speed of signal transmission in neurons.
Why can't an action potential be generated during the absolute refractory period?
Action potentials cannot be generated during the absolute refractory period, as not enough ion channels are able to respond to the stimulus, no matter how large it is. Using Na+ fast channels as an example, during depolarization the "gate" of the channel is opened, allowing for Na+ influx into the cell. However, during the repolarization phase, a second "gate" marks the closure of the cell, preventing any further movement of ions into the cell. However, this also means that the channel is unable to open again until the second gate is removed, and the first gate returns back into place.
Which of the compounds elute fast in reverse phase chromatography?
Compounds that are non-polar elute faster in reverse phase chromatography as the stationary phase is non-polar and retains polar compounds longer. Polarity of the compound determines its retention time in reverse phase chromatography.
In cardiac muscle the fast depolarization phase of action potential is the result of?
increased membrane permeability to sodium ions
What is the rising action in fast SAM cool Clyde and stuff?
The rising action in "Fast Sam, Cool Clyde, and Stuff" involves the planning and execution of Sam and Clyde's bus trip from Harlem to the 1964 New York World's Fair. As they encounter obstacles and make decisions along the way, the tension and conflict build leading up to the climax of the story - when they finally reach the fair.
What is the rising action in raymonds run?
Oh, dude, the rising action in "Raymond's Run" is basically all the stuff that happens leading up to the main conflict. It's like when Squeaky starts training for the May Day race and realizes her brother Raymond can actually run fast. So, it's all the build-up and tension before the big showdown.
How do run fast on dead rising 2?
There is no way of running on Dead Rising 2
Is fast a action?
no, fast is an adjective.

What are the phases of fast methodology?
FAST methodology typically consists of four phases: Focused, Agile, Simple, and Timely. In the Focused phase, the team identifies the key elements of the project. The Agile phase involves quickly developing and testing potential solutions. The Simple phase focuses on simplifying the solution to its most essential components. Finally, the Timely phase ensures that the project is completed within the expected timeframe.
How fast can the intervention gun shoot?
not very fast actually, it is a bolt action sniper rifle and if you want to fire it fast you better be able to reload a bolt action fast
