human_reference_atlas part of Homo sapiens organ subunit thymus lobule FMA:72215 AS thymus lobule MA:0000770 A lobule that is part of a thymus. Divided into an outer cortex and inner medulla and separated from each other by connective tissue septa, but with the medullary tissue continuous from lobule to lobule.[ncit,modified]. thymus lobule thymus lobule UMLS:C1522462 NCIT:C33772 UBERON:0002125 uberon in the mouse, the lobes of the thymus are not subdivided into lobules but only in the central medulla and a peripheral cortex (i.e. there is no distinct sublobulation). In humans, the two thymus lobes are composed of many lobules of various sizes which contain follicles, each comprising a medulla and a cortex. in the rat, the thymus is partially subdivided into lobules separated by thin bands of connective tissue which are continuous with the thin connective tissue capsule.[MP] Lymphocytes, reticular cells and macrophages are found in the lobules lobule of thymus SCTID:187882006 thymic lobule thymus lobe
