Witryna8.4 Summary. A. nerve 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. WitrynaThe 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.
WitrynaInformation from receptors passes along neurones, as electrical impulses to co-ordinators such as the central nervous system or CNS. The CNS is the brain and … WitrynaIncoming signals can be either excitatory – which means they tend to make the neuron fire (generate an electrical impulse) – or inhibitory – which means that they tend to keep the neuron from firing. Most …
