Abstract
Background: There are contradictions in the formation and structure of the various papillary muscles, their topography, functional anatomy, the structure of the trabecular meshwork, the structural features and the distribution of tendon
chords, the relationship between the structure of papillary muscle and tendon chords, and so on. D.Material: 100 heart
drugs for adults of both sexes; series of sections 60 human embryos from 6 to 70 mm parietal-coccyx length; series of
histological sections fleshy trabeculae, papillary muscle and tendon chords ventricles of the human heart (of 27 objects).
Material and methods: Anatomical, embryological, histological, morphometric, statistical.
Results: Identified structural features and distribution of tendinous chords gave opportunity to establish the relationship of the tendinous chords with the papillary muscles and cusps of the atrioventricular valves in embryogenesis and
also found in adults. First identified and described arcuate structures in the cusps valve formed by the tendinous chords.
Established stages of the intraventricular structures formation in embryogenesis defined the different number of the trabecular network layers in the left and right heart’s ventricles. The comparative characteristic which defined the functional
significance of the parameters fleshy trabeculae, papillary muscles and tendinous chords within one and between two
ventricles of the human heart was done. This experiment was based on the number of papillary muscles in a group, their
structure, methods of formation and localization before their classification was proposed.
Conclusions: On the basis of macro- and microanatomical and embryological studies we can draw an analogy conclusion that the structure of fleshy trabeculae, papillary muscle and tendon chords arcuate course in the wings of the
atrioventricular valves.
