WebThe 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 … WebTwo diseases―myasthenia gravis and Lambert-Eaton myasthenic syndrome―involve disturbances in the transmission of electrical activity across a gap (neuromuscular junction) between motor nerve endings and muscle fibers. To study them, additional short trains of nerve stimulations and needle EMG (single fiber) are used. 6.

Web8.4 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. WebSo what happens is the following: 1) A stimulus activates a receptor. 2) The receptor transmits the signal to an afferent pathway. 3) The afferent pathway carries the signal to a place (e.g. spinal cord) where this pathway synapses (or …
