Abstract: | In persons of mature, elderly and old age vascularization of the papillary muscles and tendinous chordae in the right and left cardiac ventricles has been studied depending on peculiarities of their structure and sources of their blood supply using injection, macro-microscopical, roentgenoangiographic methods, and silver nitrate impregnation. Certain data concerning the distribution zones in the papillary muscles of the coronary artery branches at various types of the cardiac blood supply are presented. Angioarchitectonics of the papillary muscles are described along their whole extention--in the basal area, in the middle part and at the apex. Architectonic peculiarities of the blood vessels in the muscular-tendinous part of the papillary muscles and in some tendinous chordae are described. |
