how the stimulated cells overcome the limitations of electrical impulses
Answers
Answer:
External electrical stimulation of nerve cells has been discovered by Luigi ... a pulse, a spike of opposite sign appears at the end. ... V is applied to the electrodes; some extra voltage is added to overcome electrode
Answer:
Functional electrical stimulation – schematic representation: Illustration of motor neuron stimulation. (a) The cell nucleus is responsible for synthesizing input from dendrites and deciding whether or not to generate signals. Following a stroke or spinal cord injury in mahnoor's muscles are impaired because motor neurons no longer receive sufficient input from the central nervous system. (b) A functional electrical stimulation system injects electrical current into the cell. (c) The intact but dormant axon receives the stimulus and propagates an action potential to (d) the neuromuscular junction. (e) The corresponding muscle fibers contract and generate (f) muscle force. (g) A train of negative pulses is produced. (h) Depolarization occurs where negative current enters the axon at the "active" electrode indicated.
