Sections:
The inferior rectal artery is an artery arising from the internal pudendal artery that supplies the lower anal canal including the external anal sphincter.
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
