Question:
What is the morphology and regions in the lymph nodes?
Author: Shay 1vccAnswer:
- T cell zone ( parafollicular cortex) - B cell zone (lymphoid follicle) - high endothelial venule HEVs enable naïve lymphocytes to move in and out of the lymph nodes from the circulatory system. HEV cells express addressins, which are specific adhesion molecules that attach to the L-selectins on lymphocytes and anchor them to the HEV wall in preparation for crossing the endothelium - afferent lymphatic vessel
