Gross anatomical examination of the pelvic cavity was performed in three male Beagle cadavers by sequential dissection from a lateral approach. The\n fossa pararectalis<\/jats:italic>\n ,\n excavatio rectogenitalis<\/jats:italic>\n ,\n excavatio vesicogenitalis<\/jats:italic>\n , and\n excavatio pubovesicalis<\/jats:italic>\n were identified by direct examination of the pelvic peritoneum and its reflections, and spatial relationships to the\n N. hypogastricus<\/jats:italic>\n ,\n N. pelvinus<\/jats:italic>\n ,\n plexus pelvinus<\/jats:italic>\n , and rectal branches were assessed. The morphology of the pelvic peritoneum was similar in all specimens, and all four recesses were consistently identified. The\n plexus pelvinus<\/jats:italic>\n was formed by convergence of the\n N. hypogastricus<\/jats:italic>\n and\n N. pelvinus<\/jats:italic>\n and was located beneath the parietal peritoneum facing the\n excavatio rectogenitalis<\/jats:italic>\n and\n fossa pararectalis<\/jats:italic>\n at the level of the\n prostata<\/jats:italic>\n . The cranial end was at the level of the\n ampulla ductus deferentis<\/jats:italic>\n and the caudal end was at the caudal end of the\n prostata<\/jats:italic>\n . Rectal branches coursed caudally beneath the parietal peritoneum along\n the excavatio rectogenitalis<\/jats:italic>\n and entered the\n rectum<\/jats:italic>\n from the ventral aspect. These findings indicate that, in male Beagles, the\n excavatio rectogenitalis<\/jats:italic>\n and\n prostata<\/jats:italic>\n represent practical anatomical landmarks for identifying the\n plexus pelvinus<\/jats:italic>\n and provide a clearer anatomical basis for topographical interpretation of the male canine pelvis.\n <\/jats:p>","DOI":"10.1111\/ahe.70141","type":"journal-article","created":{"date-parts":[[2026,6,3]],"date-time":"2026-06-03T15:07:13Z","timestamp":1780499233000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Topographical Relationship Between the\n Plexus Pelvinus<\/i>\n and Pelvic Peritoneal Reflections in Male Beagles"],"prefix":"10.1111","volume":"55","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6308-6337","authenticated-orcid":false,"given":"Motoharu","family":"Oishi","sequence":"first","affiliation":[{"name":"Laboratory of Anatomy 1, School of Veterinary Medicine Azabu University Sagamihara Kanagawa Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hirohumi","family":"Kasai","sequence":"additional","affiliation":[{"name":"Laboratory of Anatomy 1, School of Veterinary Medicine Azabu University Sagamihara Kanagawa Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tokuhiro","family":"Eguchi","sequence":"additional","affiliation":[{"name":"Laboratory of Anatomy 1, School of Veterinary Medicine Azabu University Sagamihara Kanagawa Japan"},{"name":"Vets Dental & Oral Surgery Office Fuso\u2010cho Aichi Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nobutsune","family":"Ichihara","sequence":"additional","affiliation":[{"name":"Laboratory of Anatomy 1, School of Veterinary Medicine Azabu University Sagamihara Kanagawa Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,6,3]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1532\u2010950X.1987.tb00922.x"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1159\/000144954"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/ahe.12608"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0091\u20100279(74)50051\u20106"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1439\u20100264.2003.00480.x"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.juro.2007.12.041"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/ahe.12116"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1007\/s12565\u2010021\u201000629\u20104"},{"key":"e_1_2_7_10_1","volume-title":"Miller and Evans' Anatomy of the Dog","author":"Hermanson J.
