What does the medullary cords of a lymph node contain?
The medullary cords of a lymph node contain: reticular cells, lymphocytes, macrophages and plasma cells. It is important to understand that lymphocytes include both B cells and T cells. Note also that plasma cells derive from B cells. If asked a correct answer could be B cells and also plasma cells depending on the level of the material.
What is the name of the inner region of a lymph node?
The Medulla is the inner region of a lymph node. It contains B cells, plasma cells, and macrophages.
How is it determined whether a lymph node has cancer cells?

What is the Structure of lymph node?
Lymph nodes are bean-shaped swellings that are found along the length of lymph vessels, forming clusters in the neck, armpit and groin areas. The lymph node is surrounded by a fibrous capsule, and each node is filled with a mes-like tissue (trabeculae), which slows the flow of lymph and supports the white blood cells and destroy pathogens. The nodes also contain lymphocyte nodules that are surrounded by sinuses. The node can be divided into an outer cortex and inner medulla. During infection, you may notice that the lymph nodes swell and become painful.
What is a small node of tissue that filters lymph?

What is the name of the cell that dominates in the cortical region of a lymph node?
