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. WebThe intrinsic or enteric nervous system can direct all functions of the gastrointestinal tract, even in the absence of extrinsic innervation. The enteric nervous system is located in ganglia in the myenteric and submucosal plexuses and controls the contractile, secretory, and endocrine functions of the gastrointestinal tract (see Fig. 8-3 ).
