Webb5 mars 2024 · A nerve impulse begins when a neuron receives a chemical stimulus. The nerve impulse travels down the axon membrane as an electrical action potential to the … Webb12 mars 2024 · First, since each electrical impulse generates one heartbeat, the number of electrical impulses determines the heart rate. In a normal sinus rhythm, that rate will be between 60 and 100 beats per minute. 2 The sinus node signal also controls electrical conduction as it "spreads" across the heart.
Webb21 mars 2024 · The impulse is then passed to another node within the heart – the atrioventricular node (AVN). This node is in the lower part of the right atrium. Once the impulse from the SAN reaches the AVN... WebbA nerve impulse is initiated by a stimulus, which is a change in the internal or external environment. Here, our stimulus is a lit candle. This change in environment stimulates a receptor. The receptor sends a nerve impulse to the central nervous system for …
WebbThe process starts with an action potential traveling along its axon toward the muscle to be activated. The arrival of an action potential at the axon terminal triggers an influx of calcium ions and the release of hundreds of quanta of acetylcholine simultaneously, producing an end plate potential (EPP) in the muscle.
