What else can I help you with?
For a brief time after an action potential begins a muscle fiber or neuron cannot generate another action potential This time is called the?
five second silence
What is The time an action potential begins until the resting potential has stabilized is?
1/2500 sec is the absolute refractory period.
What is a reduction in membrane potential called?
A reduction in membrane potential is called hyperpolarization. This occurs when the inside of the cell becomes more negative than the outside, making it less likely for the cell to generate an action potential.
What is the regeneration of action potential called?
The regeneration of action potential is called "propagation." It involves the transmission of the action potential along the length of the neuron's axon.
Also called a nerve impulse transmitted by axons?
action potential
A period after an initial stimulus when a neuron is not sensitive to another stimulus is the?
refractory period. This is a brief time after a neuron has fired an action potential, during which it cannot generate another action potential in response to a new stimulus. This period is crucial for maintaining the directionality of signal transmission in the nervous system.
An electrical impulse moving down an axon is called?
This is called action potential. Action potential is the change in electrical potential that occurs between the inside and outside of a nerve or muscle fiber when it is stimulated, serving to transmit nerve signals.
What is the time between the action potentials?
The time between action potentials is known as the refractory period, during which the neuron cannot generate another action potential. This period is essential to ensure that action potentials travel in one direction and allows the neuron to recover before firing again. The refractory period can vary but generally lasts around 1-2 milliseconds.
The period after initial stimulus when I neuron is not sensitive to another stimulus is the?
The period after an initial stimulus when a neuron is not sensitive to another stimulus is called the refractory period. During this time, the neuron is recovering and cannot generate another action potential, which ensures that signals are transmitted in one direction and helps maintain the integrity of the nerve signal. The refractory period can be divided into two phases: the absolute refractory period, where no stimulus can trigger an action potential, and the relative refractory period, where a stronger-than-normal stimulus is required to elicit a response.
What structure in the neuron accelerates the transmission of the action potential?
The structure in the neuron that accelerates the transmission of the action potential is called the myelin sheath.
What is the hyperpolarization that occurs after repolarizing phase of action potential?
Hyperpolarization occurs because some of the K+ channels remain open to allow the Na+ channels to reset. This excessive amount of K+ causes hyperpolarization so the Na+ channels open to bring the potential back up to threshold.
What is the interval called during which a neuron is dormant after an action potential has been completed?
Resting potential
