🐭#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)

#Astrocytes are generally depicted as #Parenchymal somas with processes reaching the #bloodvessels. Here, I show that #AstrocyteSoma are part of the #Endfeet around #PenetratingArterioles and #AscendingVenules (9/15)
