Nervous impulse
WebAs the strength of a stimulus increases, the rate of change in electrical potential of the receptor increases, and the frequency of nerve impulse generation likewise increases. The location of a stimulus, whether in the external or internal environment, is readily determined by the nervous system. WebWhat is Nerve Impulse. A nerve impulse is a coded signal that goes over the neuron membrane to stimulus cells such as muscle cells, gland cells, hormone cells, and so on. Nerve cells interact with other cells via nerve impulses to complete a certain task, and this coded signal is relayed to the neuron’s axon. Conduction of Nerve Impulse

The transmission of a nerve impulse along a neuron from one end to the other occurs as a result of electrical changes across the membrane of the neuron. The membrane of an unstimulated neuron is polarized—that is, there is a difference in electrical charge between the outside and inside of the membrane.
