- In the male it is large and of an oval form, its longest diameter slanting obliquely from before backward.
- in the female it is smaller, and more triangular.
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.
- 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 ramus of the pubis
