Figure 3. Unlike the four-chambered mammalian heart, which is driven by the muscle-derived pacemaker cells that form the sinoatrial node, the single-chambered crustacean heart is under neuronal control. The cardiac ganglion, located within the chamber of the lobster heart, contains four pacemaker neurons and five motoneurons. This simple network generates regular bursts of action potentials, which travel down the axons of the motor nerves and trigger contractions through standard chemical synapses onto heart muscle fibers. |
