Ansa cervicalis - A new classification approach.

Normally, the inferior root of Ansa cervicalis passes around the internal jugular vein and runs in an anterior direction to meet the superior root ventral to the common carotid artery. However, anatomical variants of the Ansa cervicalis are as yet not well investigated and understood. To close this gap the present study was undertaken.

[On lymphatic postcapillary].

V.V. Kupriyanov (1969) has described a new structural element within the initial segment of lymphatic bed which was given a name of "lymphatic postcapillary".

[Anatomic features of the coeliac trunk].

The study was performed in 120 specimens using preparation. According to the experimental data, from two to six branches originated from coeliac trunk. Division into three branches was the most often variant (in 60.

[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.

[Anatomo-topographic features of parasternal lymph nodes in adult humans].

The parasternal lymph nodes have been revealed in corpses of person died at the age 22-85 years by the method of preparation after Gerota's blue had been interstitially injected into the tissue of the mammary gland, the diaphragm, the diaphragmal surface of the liver, the pleura and the pericardium. The mass has also been injected into the lymph nodes and vessels revealed by means of the interstitial injection. Most of the parasternal lymph nodes are situated in interposal places, their number varying from 2 to 20 in the parasternal lymphatic chain.
