The purpose: to reveal laws of parameters variability of cross-section changeability and cross-section-outgrowth part of a vertebral artery in aspects of age variability, sexual dimorphism and a bilateral dissymmetry. Material and methods. Investigated cross-section cuts of vertebral segments with contents ofvertebral channel and channel of a vertebral artery (n=90); Kt- and MRT-grams (n=146), cervical vertebrae (n=742) complete sets with a known sex and age. The area of cross-section section was defined. Results. Age-sexual features and a bilateral dissymmetry of the area of cross-section section of a vertebral artery and cross-section apertures of cervical vertebras are revealed. Conclusion. The transverse section foramen ofvertebral arteries gradually increases with the years, apparently, at the expense of a thickening of a wall of an artery as a result of atherosclerotic damage whereas the area of section of cross-section apertures at first increases to definitive sizes, and then decreases, probably, owing to the hyperostosis phenomena. The given parameters possess sexual dimorphism and bilateral dissymmetry.
