Conclusion: In the #Brain 🧠, #Microvasculature is not #Innervated like in #PeripheralTissue. #PrecapillarySphincters and/or #FirstOrderCapillaries are central to #NeurovascularCoupling, which may be enhanced by perpendicular alignment of #NeuronalProcesses (12/15)

#MyoendothelialJunctions are 🔗s between #MuralCells and #Endothelia, elsewhere separated by the #BasementMembrane. I show how #Brain #PrecapillarySphincters are 🔥spots for these junctions (yellow dots), like Rhodin showed in 🐇 #PeripheralTissue: https://tinyurl.com/cm8chj56 (7/15)
