layers of anterior wall
(superficial to deep) |
1) skin
2) camper's fascia (fatty) 3) scarpa's fascia (membranous) 4) external obliques 5) internal obliques 6) transverse abdominal 7) transversalis fascia 8) endoabdominal fat 9) parietal peritoneum |
|
|
inguinal ligament
(formed by & location) |
formed by lower border of external oblique aponeurosis
runs from anterior superior iliac spine to pubic tubercle folding under itself to make a trough |
|
|
descent of gonads
(males) |
1) processus vaginalis forms through layers of anterior wall (acquires these layers as coverings)
2) gubernaculum (extends from inf border of gonad to labioscrotal swellings) guides the process 3) testes descend through inguinal canal along w/ vessels, ducts and nerves to form spermatic cord |
|
|
descent of gonads
(females) |
1) processus vaginalis forms through layers of anterior wall (acquires these layers as coverings)
2) gubernaculum (extends from inf border of gonad to labioscrotal swellings) guides the process 3) ovaries descend into pelvic cavity and become assoc w/ developing uterus 4) round lig of uterus passes through inguinal canal |
|
|
inguinal canal contents
(males) |
SPERMATIC CORD
-genital branch of genitofemoral nerve -cremasteric artery & vein -ductus deferens and artery -testicular artery surrounded by pampiniform plexus of veins ILIOINGUINAL NERVE |

|
inguinal canal contents
(females) |
round ligament of uterus
ilioinguinal nerve |
|
|
inguinal canal walls
|
anterior
-aponeurosis of external obliques floor -medial 1/2 of inguinal lig, rolled-under free margin of lowest part of external oblique aponeurosis (reinforced by lacunar lig where spermatic cord positioned) posterior -transversalis fascia roof -arching fibers of internal oblique and transversus abs coming to common medial attachment - conjoint tendon |
|
|

|
|
layers of spermatic cord fascia & abdominal wall equivalents
(superficial to deep) |
1) external spermatic fascia
-from external oblique & attache dto superficial inguinal ring 2) cremasteric fascia -from internal oblique and assoc w/ cremasteric mm (retracts testis) 3) internal spermatic fascia -from transversalis fascia and attached to deep inguinal ring |
