The thymus at 1 month. (A) The thymic epithilium is continuous with the pharyngeal epithilium (location of section is shown in diagram at left). (B) At higher magnification, thymocytes appear as groups of packed cells between nonlymphoid cells, including epithelial cells. Photos are of plastic sections stained with toluidine blue. B, brain; GA, gill arches; H, heart; I, intestine; O, otic vesicle; P, pharynx; T, thymus. Lymphoblasts, solid arrows marked ‘‘1’’; small lymphocytes, open arrows marked ‘‘2’’; epithelial cells, double arrowheads marked ‘‘3.’’ |
