Discuss the speed of an impulse conduction
WebNerve impulses are extremely slow compared to the speed of electricity, where the electric field can propagate with a speed on the order of 50–99% of the speed of light; however, it is very fast compared to the speed of blood flow, with some myelinated neurons conducting at speeds up to 120 m/s (432 km/h or 275 mph). WebScientists have studied how fast a neurone can transmit an electrical impulse in frogs. They use the equation: \ [\text {Speed}= \frac {\text {Distance}} {\text {Time}}\] They measured …

WebConducting cells carry the electric signals. Muscle cells control your heart’s contractions. Your heart (cardiac) conduction system sends the signal to start a heartbeat. It also sends signals that tell different parts of your heart to relax and contract (squeeze). This process of contracting and relaxing controls blood flow through your ...
