WitrynaA nerve impulse is a sudden reversal of the electrical gradient across the plasma membrane of a resting neuron. The reversal of charge is called an action potential . It begins when the neuron receives a chemical signal from another cell or some other type of stimulus . If the stimulus is strong enough to reach threshold WitrynaImpulse When a force acts on an object for a short (infinitesimally small) duration of time, it's called impulse. Impulse is the measure of how much the force changes the momentum of an object.

What is Nerve Impulse? Definition, Conduction

WitrynaConduction of nerve impulse occurs due to the presence of active and electronic potentials along the conductors. Transmission of signals internally between the cells is achieved through a synapse. Nerve conductors comprise relatively higher membrane resistance and low axial resistance. The electrical synapse has its application in … WitrynaNerve Impulse is defined as a wave of electrical chemical changes across the neuron that helps in the generation of the action potential in response to the stimulus. This transmission of a nerve impulse across the neuron membrane as a result of a change in membrane potential is known as Nerve impulse conduction.
