A functional morphometric study of the cremaster muscle microcirculation in young spontaneously hypertensive rats

In the present study, microvascular mechanisms for increased resistance were investigated in the cremaster muscle of 5-6 week-old spontaneously hypertensive rats (SHR) and age-matched Wistar-Kyoto rats (WKY) using intravital microscopy. Vessels were classified on the basis of their location in the network relative to their branching order and function (A1-A4)
