This paper is the initial report of a broader investigation of the parathyroid glands in marsupials and monotremes.<\/jats:p>Method<\/jats:italic>: Nineteen possums Trishosurus vulpecula<\/jats:italic> were used in the study of the anatomy, histology, and ultrastructure of the parathyroid glands. Tissue sections were examined using routine light and electron microscopic techniques.<\/jats:p>Results<\/jats:italic>: Parathyroid III is larger than parathyroid IV. The former occurs in the vicinity of the carotid bifurcation; the latter is found in the mediastinum, and in 67% of samples it was observed to be associated with thymic tissue. In parathyroid III specimens, 12.5% had follicles, 25% had cysts, and 16% contained thymic tissue. Ultrastructurally, the majority of specimens consisted of principal cells; no oxyphil cells were seen. Light and dark cells were only seen in glands that had been fixed by perfusion. Junctions between thymic and parathyroid tissues showed intervening epithelial reticular cells, but a basal lamina was not always apparent. In three specimens, cells that resembled water\u2010clear cells were present. It is proposed that these unusual cells may reflect a state of impaired health in these possums.<\/jats:p>Conclusions<\/jats:italic>: Except for the presence of vacuolated cells labelled water\u2010clear cells, the histology of the parathyroid gland in the possum shows many similiarities to that in many eutherians. \u00a9 1995 Wiley\u2010Liss, Inc.<\/jats:p>","DOI":"10.1002\/ar.1092410315","type":"journal-article","created":{"date-parts":[[2005,2,26]],"date-time":"2005-02-26T19:11:47Z","timestamp":1109445107000},"page":"401-410","source":"Crossref","is-referenced-by-count":4,"title":["Parathyroid morphology of the brush\u2010tail possum, Trichosurs vulpecula<\/i>"],"prefix":"10.1002","volume":"241","author":[{"given":"Julie I.","family":"Haynes","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,1,26]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/aja.1000970102"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/jmor.1051380202"},{"key":"e_1_2_1_4_1","series-title":"Third Series","first-page":"1","volume-title":"Tumours of Parathyroid Gland","author":"DeLellis R.
