11. Deep ring-
Verticaly oval shaped ,formed by condensation of
transversalis fascia , 1.25 cm abv mid inguinal
point.
Inguinal ligament-(poupart’s ligament)
Formed by lower border Of EO aponeurosis which
is thickned & folded back on itsself ,extend ASIS to
pubic tubercle

13. Content
Spermatic cord in male
Round ligament in female
Illioinguinal nerve (pierces IO n come)
Remnant process vaginalis +/-
16. Defence mechanism of inguinal canal
Obliquity of i.c ( abdmn pres; rise,oclude)
Arching of conjoint tendon-posterior wall
strengthen
Shutter mech; of internal oblique
Ball valve mech:of cremastric muscle which
plug d superior ring
Slit valve mechanism; EO contract intercrural
fiber of superficial ring appose.
23. Artery
Superior epigastric A -(internal thorasic A)
Inferior epigastric A -( external iliac A)
Deep circumflex iliac A - (external iliac A)
Superficial circumflex iliac A -(external iliac A)
Superficial epigastric A – (femoral A
26. Artery of death..
Abnormal obturator artery—
Obturator & inferior epigastric A usually gives a pubic
branch which is small & anastomos @ back of pubis
30% case, pubic branch of IEA is very large,taking d
place of obturator A & being known as abnormal
obturator A
It go down in relation to femoral ring to reach
obt.foramen
In 10% case person with such A pass down along
edge of lacunar ligament
Femoral hernia repair..some time need dividing of
this ligament cause bleeding…
32. .
Above- myoaponeurotic arch of lower edge of
IO & TA
Below –pectenial line of supra pubic ramus
Lateral-iliopsoas muscle
Medial-lateral border of rectus
Upper ½ & lower ½
Closed posteriorly by transeversalis fascia
33. Space of bogros
Located in front of peritonium beneath d
posterior lamina of transversalis fascia, it is d
lateral extension of d retropubic sps of
Retzius.
36. .
Misnomer.. Inverted V shaped area ,apex
deep ring,medial border vas deference,
lateraly by gonadal vessel,inferiorly by
external illiac vessels.
only 2 borders
Avoid staplers n suturs here.
46. Sliding hernia
A piece of extraperitoneal bowel may
slide down into i.c pulling a sac of
peritoneum with it.
Posterior wall is not form by peritoneum
alone,but by viscus which lies behind d
peritoneum
