how does transmition of nerve impulse take place??
Nerve impulse is an electrical signal that travels through the nerve cells. When there is any change in our body state which is detected by the nerve receptors, they send the information or message regarding this change through nerve impulses to the brain. Synapse exists at the end of each neuron to transmit nerve impulses from one neuron to another. It permits a neuron to pass electric impulse to another cell. At the synapse the plasma membrane of signal passing neuron comes in contact to the membrane of the neuron where the signal has to be sent. The signal is then passed through the membranes to the next neuron.
