IMF-078-01-0001-en	How can membranous superficial fascia direct urine or blood after selected urethral injuries, and what stops it descending into the thigh?	Membranous fascia continues into the perineum and channels the fluid along it, while its attachment to deep fascia of the thigh below the inguinal ligament limits descent into the limb.

IMF-078-01-0002-en	How does the rectus sheath differ above and below the arcuate line?	Above it, anterior and posterior laminae surround rectus; below it, all three broad-muscle aponeuroses pass anteriorly, leaving only transversalis fascia behind the muscle.

IMF-078-01-0003-en	Why can an abdominal incision denervate part of the wall?	Thoracoabdominal nerves from lower thoracic rami and first lumbar branches run segmentally between internal oblique and transversus to supply muscle and skin, so incisions crossing that plane can divide them.

IMF-078-01-0004-en	How does the anterior abdominal wall provide collateral flow between subclavian and external iliac territories?	Superior epigastric vessels continue from the internal thoracic within the rectus sheath and anastomose with inferior epigastric vessels from the external iliac.

IMF-078-01-0005-en	How does superficial lymph drainage of the abdominal wall differ above and below the umbilicus?	Above the umbilicus lymph drains mainly toward axillary nodes and below toward superficial inguinal nodes, while the deeper wall follows epigastric and iliac vessels.

IMF-078-01-0006-en	What trade-off distinguishes a midline linea alba incision from a transverse incision?	The linea alba is relatively avascular access but depends on durable fascial closure; transverse incisions follow skin tension and muscle planes but may cross segmental neurovascular paths.

IMF-078-01-0007-en	Why can a retroperitoneal haemorrhage or abscess produce a hip-flexion posture or femoral neuropathy?	It irritates psoas, and the lumbar plexus forms within psoas with branches emerging around it, so both the muscle and its nerves are affected.	Integrated Medical Foundations; chapter 78, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: cc393a58e56566203f1c4b955abb5979eeebf174ae460646864eb3854d5114bb; editorial review pending	imf lang::en chapter::078 module::078-01 review::pending
IMF-078-01-0008-en	Why is raised intra-abdominal pressure alone an incomplete explanation for hernia formation?	Excess pressure does not itself cause every hernia; fascial weakness, anatomy, collagen, age, previous surgery, and chronic loading also contribute.	Integrated Medical Foundations; chapter 78, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: cc393a58e56566203f1c4b955abb5979eeebf174ae460646864eb3854d5114bb; editorial review pending	imf lang::en chapter::078 module::078-01 review::pending
IMF-078-01-0009-en	What do reducibility, obstruction, and strangulation describe that the anatomical type of a hernia does not?	They describe the hernia's function and risk, whereas its anatomy is defined by sac, contents, neck, and coverings at a characteristic wall site.	Integrated Medical Foundations; chapter 78, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: cc393a58e56566203f1c4b955abb5979eeebf174ae460646864eb3854d5114bb; editorial review pending	imf lang::en chapter::078 module::078-01 review::pending
IMF-078-01-0010-en	Why is rectus diastasis not classed as a hernia, and how does its risk differ?	It is widening of the linea alba without a true fascial defect, so it alters contour and force transmission but does not create the same strangulation risk.	Integrated Medical Foundations; chapter 78, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: cc393a58e56566203f1c4b955abb5979eeebf174ae460646864eb3854d5114bb; editorial review pending	imf lang::en chapter::078 module::078-01 review::pending
IMF-078-01-0011-en	Which structures form the anterior and posterior walls of the inguinal canal, and where is each reinforced?	The anterior wall is external-oblique aponeurosis reinforced laterally by internal oblique; the posterior wall is transversalis fascia reinforced medially by the conjoint tendon.

IMF-078-01-0012-en	How does the ilioinguinal nerve enter the inguinal canal, and what does it travel with in each sex?	It enters the canal laterally rather than through the deep ring, and accompanies the spermatic cord in males and the round ligament of the uterus in females.	Integrated Medical Foundations; chapter 78, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: cc393a58e56566203f1c4b955abb5979eeebf174ae460646864eb3854d5114bb; editorial review pending	imf lang::en chapter::078 module::078-01 review::pending
IMF-078-01-0013-en	How do the inferior epigastric vessels distinguish indirect from direct inguinal hernia?	An indirect hernia enters the deep ring lateral to the vessels and may reach scrotum or labium; a direct hernia protrudes through the posterior wall medial to them in Hesselbach triangle.	Integrated Medical Foundations; chapter 78, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: cc393a58e56566203f1c4b955abb5979eeebf174ae460646864eb3854d5114bb; editorial review pending	imf lang::en chapter::078 module::078-01 review::pending
IMF-078-01-0014-en	Why does a femoral hernia carry a high risk of strangulation?	It passes below the inguinal ligament through the femoral canal, typically medial to the femoral vein, where its narrow rigid neck can constrict the contents.	Integrated Medical Foundations; chapter 78, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: cc393a58e56566203f1c4b955abb5979eeebf174ae460646864eb3854d5114bb; editorial review pending	imf lang::en chapter::078 module::078-01 review::pending
IMF-078-01-0015-en	Why is parietal peritoneal pain sharp and localised while visceral peritoneal pain is diffuse?	Parietal peritoneum has somatic innervation, whereas visceral peritoneum carries autonomic afferents that respond to distension or chemical irritation and localise poorly.	Integrated Medical Foundations; chapter 78, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: cc393a58e56566203f1c4b955abb5979eeebf174ae460646864eb3854d5114bb; editorial review pending	imf lang::en chapter::078 module::078-01 review::pending
IMF-078-01-0016-en	What distinguishes secondarily from primarily retroperitoneal organs, and why does it matter surgically?	Primarily retroperitoneal organs develop behind peritoneum; secondarily retroperitoneal ones began with a mesentery and fused to the posterior wall, leaving fusion fascia as relatively avascular planes.

IMF-078-01-0017-en	Why can pancreatic fluid collect in the lesser sac, and how does that space reach the greater sac?	The lesser sac lies posterior to stomach and lesser omentum, a space that permits gastric movement and can hold pancreatic fluid, and it communicates with the greater sac through the epiploic foramen.	Integrated Medical Foundations; chapter 78, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: cc393a58e56566203f1c4b955abb5979eeebf174ae460646864eb3854d5114bb; editorial review pending	imf lang::en chapter::078 module::078-01 review::pending
IMF-078-01-0018-en	What bounds the epiploic foramen, and what lies in its anterior boundary?	Hepatoduodenal ligament anteriorly, inferior vena cava posteriorly, caudate lobe superiorly, and first duodenum inferiorly; the ligament carries bile duct, proper hepatic artery, and portal vein posteriorly.

IMF-078-01-0020-en	Which structures does the root of the small-bowel mesentery cross along its oblique course?	Running from near the duodenojejunal junction to the ileocaecal region, it crosses distal duodenum, aorta, inferior vena cava, right ureter, psoas, and gonadal vessels.	Integrated Medical Foundations; chapter 78, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: cc393a58e56566203f1c4b955abb5979eeebf174ae460646864eb3854d5114bb; editorial review pending	imf lang::en chapter::078 module::078-01 review::pending
IMF-078-01-0021-en	Why does fluid pass more freely along the right paracolic gutter than the left?	The right gutter communicates relatively freely with hepatorenal and subphrenic spaces, whereas the left is partly limited by the phrenicocolic ligament.	Integrated Medical Foundations; chapter 78, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: cc393a58e56566203f1c4b955abb5979eeebf174ae460646864eb3854d5114bb; editorial review pending	imf lang::en chapter::078 module::078-01 review::pending
IMF-078-01-0022-en	Where does peritoneal fluid tend to collect in supine compared with upright patients?	Supine, the hepatorenal recess is dependent; upright, pelvic recesses are lowest, the rectovesical pouch in males and usually the rectouterine pouch in females.
