Baseline and maximal arteriolar diameters for in situ experiments

	Baseline Diameter* (μm)
	Control	Experimental	Maximum diameter (μm)	n
DAP	22.0 ± 2.4	19.9 ± 2.7	41.8 ± 3.1	12
BaCl2	21.7 ± 1.8	15.3 ± 1.5†	40.1 ± 2.3	14
Ouabain	20.8 ± 1.8	17.2 ± 1.5	39.3 ± 2.3‡	14
Phenylephrine	22.5 ± 2.4	15.7 ± 1.3†	46.5 ± 3.3	8

^*Baseline diameters were not significantly different across stimulus frequencies within each experiment therefore baseline diameters for 4 Hz were used as representative.

^†Significant difference from control values.

^‡Significant difference from phenylephrine maximum diameter.
