There are two named structures in the medulla:
- The medullary cords are cords of lymphatic tissue, and include plasma cells, macrophages, and B cells
- The medullary sinuses (or sinusoids) are vessel-like spaces separating the medullary cords. Lymph flows into the medullary sinuses from cortical sinuses, and into efferent lymphatic vessels. Medullary sinuses contain histiocytes (immobile macrophages) and reticular cells.
