6.28 Lymph node medulla

Version française

Section of the medulla of a lymph node.

In this section, the medullary cord (Co) is almost completely depleted of plasma cells and a large majority of the lymphoid cells are lymphocytes (L). The cellular composition of the cord thus indicates that this node is minimally reactive to antigens.

The sinuses (S) contain reticular cells (R) and lymphocytes (L). In the sinus on the right, an arteriole (A) and a venule (V) are seen in connective tissue trabecules.
