[Structuro-functional organization of the microcirculatory bed of the skeletal muscles]

Structure of the microcirculatory bed in the white rat musculus spinotrapezius and m. quadriceps femoris has been studied by means of biomicroscopic methods, as well as by means of injection and non-injection methods for revealing microvessels. Spatial arrangement of the microvessels has been followed and certain zonal functional complexes of microvessels in the muscle--myoangions--have been revealed. Polymeric-homonomous form of the microcirculatory bed organization in the muscle is substantiated. Capillary bed capacity is calculated and its reserve possibilities are estimated in the resting muscle. It has been demonstrated that geometry on distribution of functioning capillaries in the muscle is arranged in such a way that to ensure the most optimal conditions for metabolism in the muscle tissue, while keeping maximal reliability of the transorganic circulation pathways.
