Near the obturator foramen the nerve gives off an articular branch to the hip joint.
The curvature of the ischium and absence of an obturator foramen were not characteristics seen in other pachycephalosaurs.
A speech bulb, yet another type of prosthetic device often confused with a palatal obturator, contains a pharyngeal section, which goes behind the soft palate.
On the ischium there may be an obturator process and/or a proximodorsal process.
In some cases it may be downsized gradually so that tissue can strengthen over time and compensate for the decreasing size of the obturator.
Its tendon often joins with the tendons of the superior gemellus, inferior gemellus, and obturator internus muscles prior to insertion.
The prevalence of an aberrant obturator artery arising from the inferior epigastric artery is approximately 10.5%.
By the time the war ended, technology and materials had advanced sufficiently to do away with these obturator rings.
