Explanation Medullary cords in lymph nodes contain specialized cells that play a role in the immune response and B cells and plasma cells are two examples of such cells. Macrophages and T cells can also be found in the medullary cords, but they are not the primary cell types found in this area. Neutrophils and eosinophils are types of white blood cells, but they are not typically found in lymph nodes, and therefore are not typically found in medullary cords. So while B cells and T cells are both found in the medullary cords of lymph nodes, B cells and plasma cells are the most abundant and important cell types in this area.
