Surgically relevant anatomy
- Location: Intraperitoneal; mobile fixation via its own mesentery - transverse mesocolon.
- Identification: By the so-called
taeniae = taeniae coli = condensations of longitudinal muscle fibers named according to their anatomical relations as
- taenia libera (inferior)
- taenia omentalis (greater omentum)
- taenia mesocolica (transverse mesocolon)
- omental appendices = fat-filled tunica serosa
- Haustra of colon = haustrae coli = visible sacculations in the wall of the colon wall by the arrangement of the circular muscle fibers (plicae semilunares; evident on endoscopy) which are discernible on the outer wall as crescentic folds
- Definition: That segment of the colon between the splenic flexure (flexura coli sinistra) and the sigmoid colon.
- Synonym: Colon descendens
- Location: Secondarily retroperitoneal; connective tissue attachment of posterior wall with the left kidney as well as with the muscular aponeuroses of the quadratus lumborum and transversus abdominis.
- Identification: As in transverse colon, but : Cross section of the descending colon smaller than that of the ascending colon!
- Synonym: Colon sigmoideum
- Location: Between the descending colon and rectum, where it is fixed by connective tissue to the retroperitoneum and left ilium; strictly intraperitoneal; differs in course and length, usually 40cm long.
- Identification: By the taeniae (see above) which gently peter out superior to the rectum.
