Obturator membrane
Encyclopedia
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, i. e., within the margin.
Both obturator muscles
are connected with this membrane.

Obturator canal
The 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:...
