[Human lymph node asymmetry and its applied importance]

At studying various groups of the human lymph vessels (inguinal, axillary, peristernal, deep cervical, superior tracheobroncheal, etc.) a certain asymmetry in their structure has been noted. The number of similar lymph nodes at either side is not equal: their number is greater at the right side than at the left. As a rule, the range between maximum and minimum is greater in men than in women. Asymmetry of the male lymph nodes is more pronounced than that in the female. There are certain differences in size and position of the lymph nodes regarding large blood vessels. In most cases, the indices on number and size of the lymph vessels are inversely proportional. As to the microscopical structure of the lymph nodes, the asymmetry is revealed in different structure of only some structural components and separate cellular elements, which are assumed to be more labile at asymmetry of the human body functions. The data obtained on different structure of the left- and right-sided lymph nodes of the same name contribute to our knowledge on anatomy of these organs and can be used in practical medicine.
