Aim. The main purpose of research is to detect the general patterns and characteristics of the Humerus (H) systemic organization (SO) of the man’s and animals with different volumes of movements in the elbow joint at the level of it’s distal epiphysis (DE). Material and Methods. The H Bos tautus Taurus (B) R40/L40, Orycolagus cuniculus (O) - R40/L40, Canis lupus familiaris (C) - 39R/39L, Homo sapiens (H) - R77/L77 were studied using osteometry. There are 23 homologous structures were measured on each bone. A group of angular structures of the DE: corner of torsion, tilt of the diaphysis, the angle of groove of the block up to the plane of condyles. All values were analyzed involved calculating confidence intervals at α≥0.05 and multilevel Maximum likelihood factors Analysis (FA) with the rotation Equamax normalized and taking into account the lateralization of bones with the calculation of factor loads (FL). Results and Discussion. There were no differences in the magnitude of the R/L angles. The value of the twist angle varies in the O-B-H-C series from 46 to 81°. The angle of inclination of the diaphysis increases in the series H-B-O-C is from 6 to 37°. Angle of the groove of the block, representing the rotation of the lower limb-O-C-B-H is in the range 46-59°. Conclusions. The results of the study revealed the presence of a latent asymmetry of the SO of the H at the level of it’s DE, which is caused by a change in the number and volume of movements in evolution.
