[Variants in the position of the ansa cervicalis in man].
29 cadaveric specimens of head and neck obtained from adults of both sexes following fixation in 5% formaldehyde were the material for the study. 43 samples of cervical ansa were examined. The investigation demonstrated that in the majority of cases (60.5%) cervical ansa was located exterior to internal jugular vein. The variants with the high position of cervical ansa in respect to the upper margin of thyroid cartilage were found in the samples with cervical ansa lying interiorly to the internal jugular vein.
