The Branching Pattern of the Nervus Ischiadicus after Passing through the Foramen Ischiadicum Majus in Hasak Sheep Breed

摘要

Background: Hasak is a sheep breed, developed as a result of crossbreeding studies at Bahri Dagdas International Agricultural Research Institute. The aim of this study was to examine the macroanatomical structure of the nervus ischiadicus outside the cavum pelvis in Hasak sheep breed. Methods: 5 Hasak sheep were used for this study. After opening the body cavities of the cadavers, they were fixed in formaldehyde solution. The branches of the nervus ischiadicus were dissected separately and photographed. Result: It was observed that nervus ischiadicus was emitting nervus gluteus caudalis immediately after leaving the foramen ischiadicum majus. After this branching nervus ischiadicus coursed ventrally and it was divided into two nerves: nervus tibialis and the common root of nervus peroneus communis and nervus cutaneus surae caudalis.
