Initiation of nerve impulses

WebbThe nerve impulse is a wave of depolarization traveling along the axon of the motor nerve such that the resting membrane potential of about −70 millivolt is reversed, becoming briefly positive. At the nerve terminal, … Webb3 apr. 2024 · What is the first step of a nerve impulse? Nerve impulses begin in a dendrite, move toward the cell body, and then move down the axon. A nerve impulse travels along the neuron in the form of electrical and chemical signals. The axon tip ends at a synapse. A synapse is the junction between each axon tip and the next structure.

Webbnerve impulse is an electrical phenomenon that occurs because of a difference in electrical charge across the plasma membrane of a neuron. The sodium-potassium pump maintains an electrical gradient across the plasma membrane of a neuron when it is not actively transmitting a nerve impulse. This gradient is called the resting potential

WebbA nerve impulse is the electric signals that pass along the dendrites to generate a nerve impulse or an action potential. An action potential is due to the movement of ions in and out of the cell. It specifically involves sodium and potassium ions.
