Document Summary
Anatomy exam 2: ligaments / fissures / spaces. 1. 5 muscles (aponeuroses of external oblique and half of internal oblique) above rectus abdominis and 1. 5 muscles (aponeuroses of half of internal oblique and transversus abdominis) beneath rectus abdominis. All 3 aponeuroses of 3 above muscles are above the rectus abdominis muscle. Transmits the spermatic cord (male) and round ligament of the uterus. Bound by lower margin of transversalis fascia, below and inferiorly by internal epigastrics. Formed by the 3 abdominal muscles (both obliques and transversus abdominis) Passage to anterior conveying the spermatic cord and round ligament. Above medial inguinal ligament superior wall (roof): internal oblique transversus abdominis anterior wall: aponeurosis of external oblique aponeurosis of internal oblique posterior wall: transversalis fascia conjoint tendon inferior wall (floor): inguinal ligament lacunar ligament. One way to remember these structures is with the mnemonic malt, starting at the top and going counterclockwise: Ilioinguinal nerve (doesn"t pass through deep ring; instead joins between transversus.
