Witryna10 lip 2024 · Nerve impulses, or action potentials, are electrochemical impulses that cause neurons to release electrical or chemical signals that initiate an action potential in another neuron. Nerve impulses are received at neuronal dendrites, passed through the cell body, and are carried along the axon to the terminal branches. WitrynaNerve impulse refers to a signal driven by either electrical, chemical or mechanical stimulus onwards the segment of an axon filament. It generates a change in the potential gradient of voltage-gated channels across the membrane, resulted from ionic movement in and out of the axolemma. inear supper bass metal earbuds earphone
