WebNervous Transmission. When a neuron is not actively transmitting an impulse it is said to be resting. Potential difference across axon membrane is resting potential when a neuron is in resting state. The axon is said to be polarised as there is a potential difference - usually -70mV. Resting potential occurs because of the movement of sodium ...

WebWhen you want your hand to move, your brain sends signals through your nerves to your hand telling the muscles to contract. But your nerves don’t just say “hand, move.”. Instead your nerves send lots of electrical impulses (called action potentials) to different muscles in your hand, allowing you to move your hand with extreme precision. WebConduction 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 …
