Rapid onset vasodilation (ROV) in response to single tetanic contractions in WT and Cav2^−/− mice. For all vessel branch orders, ROV increased with contraction duration and was attenuated in Cav2^−/− compared with WT mice. Summary data are means ± SE; n = 5 per group. *P < 0.05 for Cav2^−/− vs. WT at indicated contraction duration. #P < 0.05 for groups across contraction durations. Respective diameter changes (μm) are shown in Fig. 8.
