History of Bioelectrical Study and the Electrophysiology of the Primo Vascular System

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, Ca^2+ ion channel)	[37]
	Patch clamp,; Current-voltage relationship	Four types	Nonexcitable cell; (K^+ 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]
