: 1. The external oblique aponeurosis divides into the anterior and posterior lamina at the linea semilunaris.
: a. False: internal oblique aponeurosis divides Agree. What does divide at linea semilunaris and above what level?
: 2. Inferior to the arcuate line, the rectus abdominis muscle is in contact with extraperitonal connective tissue.
: a. True: via the transversalis fascia Disagree with "True." Thus, False. Direct contact with TF.
: 3. The inferior epigastric artery anastomoses with the internal thoracic artery within the rectus abdominis muscle.
: a. False: anastomoses w/ superior epigastric artery from internal thoracic artery Agree. What anastomoses with musculophrenic artery?
: 4. Inferior to the arcuate line, the aponeuroses of the external oblique, internal oblique, and transversus abdominis muscles pass posterior to the rectus abdominis muscle.
: a. False: runs anterior to rectus abdominis muscle Agree. See #2.
: 5. The umbilicus is typical at the L3 vertebral level and the T10 dermatome level.
: a. True Agree. Referred pain midgut.
: 6. The xiphoid process is at the T8/9 vertebral level and the T6 dermatome level.
: a. True Agree. Referred pain foregut.
: 7. Preganglionic fibers arising from the intermediolateral cell column at spinal cord levels T5-9 travel within the greater splanchnic nerve and impact stasis along the same regions of the alimentary canal that receive arterial supply by way of the celiac trunk.
: a. True Agree. Know what you know when you know something.
: 8. Nociceptive information from the foregut travels to cord levels T5-9 by way of the greater splanchnic nerves.
: a. True Agree.
: 9. The gall bladder is an organ of the foregut.
: a. True Agree.
: 10. Nociceptive information from the gall bladder is expected to travel to cord levels T5-9.
: a. True Agree.
: 11. Referred pain from the gall bladder and liver may occur at and near the xiphoid process.
: a. True Agree. Please make the connection implied by #5-11.
: 12. The potential space defined by the attachments of Scarpa's fascia has its superior extent at the level of the xiphoid process.
: a. False: ends slightly inferior to the umbilicus Agree. May have "finger like" extensions slightly above umbilicus.
: 13. All borders of the superficial ring are defined by derivatives of the external oblique aponeurosis.
: a. False: Anterior: EO aponeurosis (intercrural fibers) Disagree. This is a dicey question. Borders of the "ring." True. Conjoint tendon is relationship to ring; not border. Floor (arrgh - inferior) is reflected inguinal ligament.
: i. Posterior: inguinal falx (conjoint tendon)
: ii. Floor: lacunar ligament
: iii. Roof: EO aponeurosis (medial crus)
: 14. The origin of the transversus abdominis muscle is from the lateral third of the inguinal ligament and the origin of the external oblique is from the lateral two-thirds of the inguinal ligament.
: a. True Agree. Know what this means about the tunics of the spermatic cord.
: 15. The inferior free edge of the transversus abdominis muscle passes superior to the deep ring.
: a. True: makes the roof and posterior wall of deep inguinal ring Agree. But the walls of the deep ring are transversalis fascia. Superior relationship is inferior free edge of transversus abdominis.
