- periarterial lymphatic sheath (PALS)
What struture are chiefly T lymphocytes in initial formation of white pulp (lymphatic nodules)
- periarterial lymphatic sheath (PALS)
What structure that is a deeper extension of the cortex, no lymphatic nodules, diffuse lymphatic tissue, mostly T cells
Paracortex
What does the paracortex contain?
High endothelial venules
What are high endothelial venules (HEV)
Specialized post capillary venules, entry point for most circulating lymphocytes
Which type of nodule has an immune response to antigen presentation
Secondary lymphatic nodules
What has a paler germinal center of proliferating lymphocytes, mostly B cells
Secondary lymphatic nodules
What is surrounded by corona (mantle) of smaller mature B lymphocytes (cells
Secondary lymphatic nodule
What type of structure is immediately below the capsule and receives lymph from the
afferent lymphatics
Subcapsular sinus
In the spleen, it contains a trabecular that consist of what
Myofibroblast
What is the function of the myofibroblast
Contractile, help in release of RBC storage pool when necessary
Epithelioreticular cells are features of what type
Reticular cells and epithelial cells
What are supportive cells with no true CT fibers within a thymic lobule
Epithelioreticular cells
What is the function of the Epithelioreticular cells
Line capsule, trabeculae, and surround microvasculature helping to form blood–thymus barrier
