What are two of the subdivisions of the lymphatic nodule?

• A. Medulla and cortex
• B. Adenoids and spleen
• C. Thymus and lymph nodes
• D. Follicles and sinuses

Answer: (A)

The correct answer highlights that the medulla and cortex are indeed subdivisions of lymphatic nodules, which are integral components of lymphoid tissues.

In lymphatic nodules, the cortex represents the outer region that is densely packed with lymphocytes and is primarily involved in the initial immune response. The medulla, on the other hand, is the inner region that often contains fewer lymphocytes and is home to the medullary cords and sinuses where antibody-producing plasma cells can be found. This division allows for organization within the lymphatic tissue, facilitating efficient immune system functions.

Understanding the structural composition of these nodules is crucial in appreciating how lymphatic tissues filter lymph and mount immune responses. Other options do not represent subdivisions of lymphatic nodules; instead, they include components or organs of the lymphatic system that serve different roles.
