WebDec 26, 2024 · The pathway of a nervous impulse is from one neuron to the next until it reaches skeletal, cardiac or smooth muscle. The impulse begins or is propagated from the nerve cell body or the axon hillock to be precise and travels to either another neuron synapse or a terminal bouton at the neuro-muscular junction. WebMuscle 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 heart and to the rest of your body.
