Boundaries
A first-order approximation is to visualize the canal as a cylinder,
To help define the boundaries, the canal is often further approximated as a box with six sides. Not including the two rings, the remaining four sides are usually called the "anterior wall", "posterior wall", "roof", and "floor". These consist of the following:
| superior wall (roof): transversus abdominis internal oblique medial crus of external oblique muscle |
||
| anterior wall: aponeurosis of external oblique fleshy part of internal oblique (lateral third of canal only) superficial inguinal ring (medial third of canal only) |
(inguinal canal) | posterior wall: transversalis fascia conjoint tendon (Inguinal falx,reflected part of inguinal ligament, medial third of canal only) deep inguinal ring (lateral third of canal only) |
| inferior wall (floor): inguinal ligament lacunar ligament (medial third of canal only) iliopubic tract (lateral third of canal only) |

Famous quotes containing the word boundaries:
“Not too many years ago, a child’s experience was limited by how far he or she could ride a bicycle or by the physical boundaries that parents set. Today ... the real boundaries of a child’s life are set more by the number of available cable channels and videotapes, by the simulated reality of videogames, by the number of megabytes of memory in the home computer. Now kids can go anywhere, as long as they stay inside the electronic bubble.”
—Richard Louv (20th century)
“The boundaries which divide Life from Death are at best shadowy and vague. Who shall say where the one ends, and where the other begins?”
—Edgar Allan Poe (1809–1845)
