title: [Capillaries of the intrinsic nerves of human skeletal muscles].
abstract: Development of blood capillaries in the human intraorganic nerves has been studied. The intramuscular nerves of fetuses, newborns, children and mature persons (88 cases in all) make the object of the investigation. Combination of light optic methods and electron microscopy is used. The development of blood capillaries of the human intraorganic nerves is a complex process, indissolubly connected with development of myelin and amyelin conductors. The capillaries in the nerves appear on the 3d month of the intrauterine development and their structure is the most favourable for intensively proceeding, at this time, the myelinization process. With progress of nervous fibers and stromal elements, differentiation of the blood capillaries takes place. By the 6th month of the interuterine life, the capillaries of the intramuscular nerves are mainly formed. The structural unit in interrelation of the capillaries and nerve elements is the complex: capillary-lemmocyte-nervous fiber. Further changes are of slower character.
