The ischiopubic ramus is the branch between which bones?

• A. Branch between sitting bone and frontal hip bone
• B. Branch between ilium and pubis
• C. Branch between sacrum and ilium
• D. Branch between ischium and pubis

Answer: (A)

The ischiopubic ramus is the bridge that connects the ischium (the sitting bone) to the pubis (the frontal part of the hip bone). It’s formed by the union of the inferior ramus of the pubis with the ramus of the ischium and helps form the lower boundary of the obturator foramen. So the ischiopubic ramus lies between the ischium and pubis. Other pairings describe connections like the sacroiliac joint (sacrum with ilium) or the iliopubic region, which are not what the ischiopubic ramus represents.
