A number of specialised tissues are important for the proper functioning of the immune system. Understanding the histomorphologic features of the lymphoid lobule and the role of the reticular meshwork scaffolding of the lymph node and how these related to the cortex, paracortex and medulla provides a unique approach to understanding lymph node structure and function.
