Summary
origin: from internal pudendal artery, just after it enters the pudendal canal
course: runs anteromedially through the ischioanal fossa to reach the deep portion of the external anal sphincter
termination: divides into multiple branches to supply the muscles and integument of the lower anal region
anastomoses: with superior and middle rectal arteries and with contralateral inferior rectal artery branches
