Lymph node: medulla
The medulla contains medullary cords and medullary sinuses located between the cords. The medullary cords are composed primarily of B lymphocytes and plasma cells along with macrophages, lymphocytes and reticular cells. The lymph-filled medullary sinuses contain macrophages, lymphocytes and a network of reticular cells and fibers. 200x
