| Abstract: | A relative density of acetylcholine esterase-reactive fibers in adventitium of the large subcutaneous vein changes in the postnatal ontogenesis in women: it is the lowest in newborns, the greatest in mature women, in old women it grows small. In newborns these fibers are situated in the compact layer of the adventitium, in mature and old women they are revealed in interlayers of the connective tissue that separate fasciculi of muscle fibers of the external longitudinal and internal circulatory layers of the middle sheath. |
