Table 4
The summarization of the electrophysiological properties of the primo vascular system.
| Target | Methodology | Cell Type | Result | Reference |
| Primo node | Intracellular recording | Vascular smooth muscle like | Excitable (Muscarinic receptor, ion channel) | [37] | Patch clamp, Current-voltage relationship | Four types | Nonexcitable cell ( ion channel for Type I) | [43] | Extracelluar recording | Two types | Excitable cell (not smooth muscle like) | [45] |
| Primo duct | Intracellular recording | Smooth muscle Secreting cell Immune cell | Excitable Non-excitable | [44] |
