[Cellular composition of the deep cervical and apical axillary lymph nodes in mature and aged humans].

Quantitative investigation of the cellular composition of follicles, cortical plato and myelinated strands of the regional lymphatic nodes in man has shown the lymphocytes (small, medium-size and large) to be prevailing cellular elements in all structural components of the node. Among them there are many small lymphocytes. In myelinated strands there are more reticular, plasma, mast cells and macrophages than in the cortical plato of the lymphatic node. The follicles of the lymphatic nodes are more homogeneous structural components. They consist mainly of lymphocytes. The cellular composition of profound cervical and apical axillary lymphatic nodes is different in the quantitative contact of cellular elements. It also changes depending on age and symmetry.
