🐭#Brain #Microvasculature is not #Innervated. But #Parenchymal #NeuronalProcesses arrange perpendicular to #Arteriole direction where #PerivascularSpace exists, while #AscendingVenules do not have this arrangement (10/15)

#Collagen is mainly synthesized by #Fibroblasts, strengthening #Arteriole and #Capillary vessel wall. #Ultrastructure shows #fibripositors where #collagenfibril #tripelhelixes are made and #fibrils that reach across the #PerivascularSpace (8/15)

‼️Importantly, #PrecapillarySphincters exist where a #Capillary branches from a much larger #Arteriole (≈upper cortical layers) but not when there is a more gradual transition (≈lower cortical layers). (3/15)

Introduction: Precapillary sphincters are indentations of the #capillary lumen at where it branches from an #arteriole. With colleagues I have previously shown their location 🗺️ and function 🧑‍🔧 (https://tinyurl.com/euasfses). (2/15)
