- Obturator arteryObturator arteryThe obturator artery is a branch of the internal iliac artery that passes antero-inferiorly on the lateral wall of the pelvis, to the upper part of the obturator foramen, and, escaping from the pelvic cavity through the obturator canal, it divides into both an anterior and a posterior...
- Obturator nerveObturator nerveThe obturator nerve in human anatomy arises from the ventral divisions of the second, third, and fourth lumbar nerves; the branch from the third is the largest, while that from the second is often very small.-Path:...
- Obturator vein
- Obturator externus muscleObturator externus muscleThe obturator externus muscle is a flat, triangular muscle, which covers the outer surface of the anterior wall of the pelvis.It is sometimes considered part of the medial compartment of thigh, and sometimes considered part of the gluteal region....
- Obturator internus muscleObturator internus muscleThe obturator internus muscle originates on the medial surface of the obturator membrane, the ischium near the membrane, and the rim of the pubis.It exits the pelvic cavity through the lesser sciatic foramen....
- Obturator membraneObturator membraneThe obturator membrane is a thin fibrous sheet, which almost completely closes the obturator foramen.Its fibers are arranged in interlacing bundles mainly transverse in direction; the uppermost bundle is attached to the obturator tubercles and completes the obturator canal for the passage of the...
- Obturator canalObturator canalThe obturator canal is a passageway formed in the obturator foramen by part of the obturator membrane. It connects the pelvis to the thigh.The obturator artery, obturator vein, and obturator nerve all travel through the canal.-Pathology:...
- Obturator foramenObturator foramenThe obturator foramen is the hole created by the ischium and pubis bones of the pelvis through which nerves and muscles pass.- General structure :...
- Palatal obturatorPalatal obturatorA palatal obturator is a prosthesis that totally occludes an opening such as an orinasal fistula . They are similar to dental retainers, but without the front wire. Palatal obturators are typically short-term prosthetics used to close defects of the hard/soft palate that may affect speech...
, a prosthetic device to close an opening in the palate
In botany:
- Part of the ovary of a flower that chemically guides the pollen tube to the micropyle
In engineering:
- Obturator ringObturator ringObturator rings are a specific type of piston ring used in World War I aero engines to compensate for warping of the cylinders.-Purpose:The rotary aircraft engines of World War I were notoriously difficult to keep cool when operating...
, a part in early aircraft engines - An obturating valve is a valve designed to be able to vary the flow of the fluid passing through it.
