Note also the plasma cells with their characteristic, eccentrically located nucleus, heterochromatin, basophilic cytoplasm, and negative Golgi. The lymph nodes usually lie within adipose tissue. Find the area outside the capsule and identify individual adipocytes. Using an atlas, identify the cortex and medulla of the lymph node. The collagenous connective tissue septa that extends from the capsule through the cortex and into the medulla supports the vasculature of the node.
Lymphocytes have a dense nucleus with little cytoplasm.
In addition to lymphocytes, the spaces or sinuses located between these cords of cells contain both stellate reticular cells and macrophages. The macrophages are large cells with cytoplasmic vacuoles. An inflammation of the Fallopian tube is called salpingitis. Salpingitis can be caused by many pyogenic microorganisms, but the most common cause are gonococci. On this slide, the lumen and mucosa of the Fallopian tube is heavily infiltrated by connective tissue cells.
