Final answer:
The superior ramus is a segment of bone that passes laterally from the pubic tubercle towards the AIIS; the actual distance is not specified in the question.
Step-by-step explanation:
The student has asked about the bony structure involving the pubic tubercle and the anterior inferior iliac spine (AIIS). The superior pubic ramus is a segment of bone that extends from the body of the pubis to where it joins the ilium.
Extending laterally from the pubis, the superior pubic ramus connects to the AIIS, which is located on the ilium. The precise distance is not mentioned in the question, but the superior pubic ramus itself is a narrow bone extension that spans between these two points.
