Medulla of lymph node Anatomy
This structure is constituted by cord-shaped lumps of lymphocytes that are separated by lymph sinuses. It is composed of two types of structures:
These are lymphatic tissue cords and are comprised of B cells, macrophages, and plasma cells.
Also known as sinusoids, these are vessel-shaped spaces that keep the medullary cords isolated. These contain reticular cells and histiocytes (macrophages that are incapable of movement).
