Histologie Lymphatische Organe (Lymphknoten, Milz, Tonsillen, GALT, Thymus) - AMBOSS Video

The histology of secondary lymphatic organs and the thymus (primary lymphatic organ) is the subject of this episode of the AMBOSS Histo-Trainer. In this hands-on histology tutorial, we show you how to differentiate between lymph nodes, the spleen, and mucosa-associated lymphatic tissue (MALT) – consisting of tonsils/NALT and GALT. We also discuss the pediatric and adult thymus. To optimally prepare you for the oral examination using the microscope, for example, in the medical examination (Physikum) or during the histology semester, we also provide you with a helpful mnemonic at the end for reliable organ diagnosis of lymphatic organs.
