In rectus sheath, branch of which aery makes an anastomosis with superior epigastric aery: (A) Subclan Aery, (B) External iliac Aery, (C) Internal iliac Ae, (D) Common iliac aery
Answer is B. Within the rectus sheath, there is anastomosis between superior epigastric aery (a branch of the internal thoracic aery) and inferior epigastric aery (a branch of the external iliac aery). The external iliac aeries are branches of the common iliac aery, which is, in turn, a branch of the abdominal aoa.
