Lymph nodes have a capsule and trabeculae. Lymphatic vessels enter
the node at various points, penetrating the capsule. Inside the
lymph node are two general regions, an outer cortex and an inner
medulla. Identify these and their components on this slide of a
single large LYMPH NODE. The little box in
the picture to the left is seen enlarged below.
- The cortex has numerous trabeculae and densely packed
lymphocytes, often as lymphatic nodules
(also called lymphoid follicles).
- The medulla is composed of larger interconnected sinuses
(spaces) and a meshwork of trabeculae giving this region a
lighter staining appearance.

In these images, you can see the
lymphatic follicles in the cortex, some demonstrating germinal center
formation.
