title: [Ultrastructure of the blood supplying capillaries of the sciatic nerve in rats].
abstract: Electron microscopic studies of the capillaries in the epi-, peri- and endoneurium of the rat sciatic nerve revealed that the capillaries in question possess the features common to the construction of this category of vessels in other organs. In epineurium and perineurium there are capilaries with somatic and visceral types of endothelium. Endoneural capillaries have endothelium of somatic type with ultrastructural features demonstrating its barrier properties. This specificity of endoneural capillaries endotheilum is connected with peculiarities of hemato-neuronal barrier of the peripheral nerves, to which endothelium is an integrated part.
