In normal state cortical substance is represented by
slightly chromogenic (almost achromogenic – 1-2 points at Fleindler’s scale)
homogeneous frame. Central parts (trabecules, parachylarious thickening, fatty
inclusions, partially – medullary substance) are represented by hypochromogenic
structure (2-3 points), portal – by homogeneous hypochromogenic structure of
irregular (triangular) shape.
Structure of lymph nodes changes depending on their
location. So, at analysis of structure of cervical lymph nodes located close to
an organ, we see that the closes to an organ lymph nodes (non-permanent) are of
smaller size, have roundish or spindled shape, and lesser presence of cortical
substance. In lymph nodes located far from an organ cortical substance is
developed better.
