Document Summary

Lab 5: lymphoid system: lymph node (25-1, 25-3) Dense ct trabeculae arising from capsule often find blood vessels in trabeculae. Cortex: numerous lymphoid nodules; germinal centers (pale), crown of lymphocytes (darker stain) Subapsular sinus (b/w capsule & cortex) cortical sinuses (along trabeculae, b/w nodules) medullary sinus. Medulla: medullary cords (small lymphocytes) separated by medullary sinuses (pale staining areas in medulla: thymus (27-1, 27-2, 27-3) Relatively thin dense ct capsule septae: divides into incomplete lobules. Medulla: light staining, abundant reticular epithelial cells (large, pale staining nucleus) Hassall"s (cid:272)orpus(cid:272)les (circular, concentric rings of cells, center = dead cells) Splenic sinusoids (lighter stain: spleen (28-1, 28-2, 28-6) Thick dense ct capsule trabeculae: divides into incomplete compartments (bvs in trabeculae) White pulp: central arteries surrounded by periarteriolar lymphatic sheath (pals) = t-cells. Splenic cords (cords of billroth, darker stain: tonsils (26-1) Aggregates of incompletely encapsulated lymphoid tissues under epithelium. Mucosal glands to clean crypts to prevent blockages.
