Inferior Mesenteric Artery 3D

  • Description                                              
    • * Passes to the left behind the peritoneum and distributes to the descending and sigmoid colons and the upper portion of the rectum.
    • * Gives rise to left colic, sigmoid, and superior rectal arteries.

 

  • Left Colic Artery:
    • * Runs to the left behind the peritoneum toward the descending colon and divides into ascending and descending branches.

 

  • Sigmoid Arteries​​​​​​​:                                            
    • * Are two to three in number, run toward the sigmoid colon in its mesentery, and divide into ascending and descending branches.

 

  • Superior Rectal Artery​​​​​​​:                                            
    • * Is the termination of the inferior mesenteric artery.
    • * Descends into the pelvis, divides into two branches that follow the sides of the rectum, and anastomoses with the middle and inferior rectal arteries.
