2.3 POJA-L1031
Title: Lymph node (rat)
Description: Electron microscopy.
A low magnification of a part of the medulla showing medullary cords surrounded by labyrinthine medullary sinus (*).
In this picture the medullar cord runs from left bottom corner to right top corner, and is lined by flat reticular cell types. Within the cord one finds a star-shaped reticular cell (1), lymphocytes (2), young plasma cells (3) and a cross-sectioned ascending arterial capillary with one erythrocyte (4) in it. Ascending branches of the arterial supply from the hilum always traverse within the cords.
The sinuses are lined by flat littoral cells (5) containing dense lysosomes. The sinuses are also filled with different types of lymphocytes (8), reticular cells (6), phagocytising reticular cells (7) and macrophages (9). At (→) openings between the lining cells where passages of various cells occur.
Keywords: lymphatic tissue, lymph node, medulla, littoral cell, reticular tissue, reticular cell, phagocytosis, histology, electron microscopy, POJA collection.
