superior ramus การใช้

It passes laterally and downward from the medial end of the superior ramus.
The "'superior ramus "'is a partial origin for the internal obturator and the external obturator muscles.
The Medial Portion of the superior ramus, formerly described as the body of the pubis, is somewhat quadrilateral in shape, and presents for examination two surfaces and three borders.
The lesser pelvis is bounded in front and below by the pubic symphysis and the superior rami of the pubes; above and behind, by the sacrum and coccyx; and laterally, by a broad, smooth, quadrangular area of bone, corresponding to the inner surfaces of the body and superior ramus of the ischium, and the part of the arcuate line.
