Obturator Membrane , i. e., within the margin.
Both obturator muscles are connected with this membrane ...
The 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 vessels and nerve. The membrane is attached to the sharp margin of the obturator foramen except at its lower lateral angle, where it is fixed to the pelvic surface of the inferior ramus of the ischium The ischium () form ...

Obturator Foramen
The obturator foramen (Latin foramen obturatum) is the large opening created by the ischium and pubis (bone), pubis bones of the pelvis through which nerves and blood vessels pass. Structure It is bounded by a thin, uneven margin, to which a strong membrane is attached, and presents, superiorly, a deep groove, the obturator groove, which runs from the pelvis obliquely medialward and downward. This groove is converted into the obturator canal by a ligamentous band, a specialized part of the obturator membrane, attached to two tubercles: * one, the posterior obturator tubercle, on the medial border of the ischium, just in front of the acetabular notch * the other, the anterior obturator tubercle, on the obturator crest of the superior pubic ramus, superior ramus of the pubis (bone), pubis Variation Reflecting the overall sex differences in human physiology, sex differences between male and female pelvises, the obturator foramina are oval in the male and wider and more triangular ...

Obturator Canal
The obturator canal is a passageway formed in the obturator foramen by part of the obturator membrane and the pelvis. It connects the pelvis to the thigh. Structure The obturator canal is formed between the obturator membrane and the pelvis. The obturator artery, obturator vein, and obturator nerve all travel through the canal. Clinical significance An obturator hernia is a type of hernia involving an intrusion into the obturator canal. The obturator nerve can be compressed in the obturator canal. The obturator canal may be compressed during pregnancy and major traumatic injuries, causing obturator syndrome. See also * Obturator fascia The obturator fascia, or fascia of the internal obturator muscle, covers the pelvic surface of that muscle and is attached around the margin of its origin. Above, it is loosely connected to the back part of the arcuate line, and here it is conti ... References External links Pelvis {{Anatomy-stub ...

Inferior Ramus (other)
Inferior ramus may refer to: * Inferior ramus of the ischium * Inferior pubic ramus In vertebrates, the pubic region ( la, pubis) is the most forward-facing (ventral and anterior) of the three main regions making up the coxal bone. The left and right pubic regions are each made up of three sections, a superior ramus, inferior ra ... {{disambig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ischium
The ischium () forms the lower and back region of the (''os coxae''). Situated below the ilium and behind the pubis, it is one of three regions whose fusion creates the . The superior portion of this region forms approximately one-third of the acetabulum. |
Obturator Muscles (other)
Obturator muscles may refer to: * External obturator muscle * Internal obturator muscle The internal obturator muscle or 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. The i ... {{disambig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
