middle rectal artery การใช้

The middle rectal artery usually arises with the inferior vesical artery, a branch of the internal iliac artery.
Blood is supplied to the vagina via the branches of the uterine artery, the middle rectal artery, and the internal pudendal artery, all branches of the internal iliac artery.
These pierce the muscular coat of the bowel and run downward, as straight vessels, placed at regular intervals from each other in the wall of the gut between its muscular and mucous coats, to the level of the internal anal sphincter; here they form a series of loops around the lower end of the rectum, and communicate with the middle rectal artery ( from the internal iliac artery ) and with the inferior rectal artery ( from the internal pudendal artery ).
