Where does the internal iliac artery terminate?

Where does the internal iliac artery terminate?

• A. Superior edge of the greater sciatic foramen by dividing into anterior and posterior divisions
• B. At the pelvic brim
• C. Within the inguinal canal
• D. At the bifurcation of the common iliac artery

Answer: (A)

The internal iliac artery ends by dividing into an anterior and a posterior division at the superior border of the greater sciatic foramen. This division near the top edge of the greater sciatic foramen distributes its branches to the pelvic organs, pelvic walls, and gluteal region. It does not terminate at the pelvic brim, within the inguinal canal, or at the bifurcation of the common iliac artery.
