Explanation
Trabeculae: These are thin connective tissue strands that extend from the capsule of the lymph node into the interior. They help to divide the lymph node into distinct compartments or regions, which include the cortex (outer area) and medulla (inner area). This compartmentalization is important for the organization and function of the lymph node, allowing it to efficiently filter lymph and facilitate the immune response.
