[Anatomy of the connective tissue framework of adult human lymph nodes]

The morphometrical investigation of thin histological sections taken from the profound inferior cervical, apical axillary, superior and inferior tracheobronchial and ulnar lymph nodes of adult man has demonstrated the amount of the connective tissue in the nodes to be increased with age. At the same time, the amount of parenchyma in the node is somewhat decreased, the correlation between the medullary and cortical substance being also changed. There are some sex differences in the connective tissue construction. The amount of the connective tissue in the lymph node in men is 2-3% more than that in women. Women have more adipose tissue than men. The developmental transformation and seasonal changes in the connective tissue correlate with the cytoarchitectonics of lymph nodes and the changes of their parenchyma.
