Inguinal Region Flashcards
gubernaculum
“governs” descent of testis/ovary
in female, ovarian ligament attaches ovary to uterus round ligament attaches to skin of labia
testis wrapped with what tissue?
processus vaginalis forms?
drags what bundle along with it?
parietal peritoneum
TUNICA VAGINALIS
duct, vessels, and nerves = SPERMATIC CORD
tunnel along body wall called?
inguinal canal
testicular descent through which body wall/tissue layers? what do these layers become?
parietal peritoneum
trasversalis fascia –> int spermatic fascia
transverses abdominis (gap)
internal oblique –> cremaster
external oblique –> ext spermatic fascia
scarpa’s fascia –> dartos
skin
trasversalis fascia binds what two tissues?
parietal peritoneum with transverses abdominis
inguinal canal between?
peritoneum and trans fascia
this is where vessels travel (and VD)
cremaster muscle is extension of which muscle?
internal oblique
testis passes through inferior edge of internal oblique and brings it along (SKELLETAL muscle)
superficial/deep inguinal rings
what emerges from here?
where aponeuroses of ext. obl. separate (sup)
spermatic cord
inferior edge of external oblique aponeurosis forms what? attaches where?
inguinal ligament
attaches to ASIS and pubic tubercle
which abdominal muscle is not affected by descent?
transversus
inferior edge of muscle is above spermatic cord
what muscle surrounds spermatic cord?
external oblique
conjoint tendon does what? which two muscles compose it?
reinforces inguinal triangle
combined tendon for transversus and int oblique
weak areas?
underneath the conjoint tendon
at the deep inguinal ring
ESPECIALLY with a patent processus vaginalis
inguinal triangle boundaries?
rectus abdominis
inferior epigastric
inguinal ligament
how to repair an inguinal hernia?
can push back in OR
incise anterior rectus sheath, pull conjoint tendon and suture
neuromuscular bundles to thigh pass through what?
gap between bone of pelvis and inguinal ligament
another weak site
femoral artery/vein begins where? drags what with it?
begin when pass under inguinal ligament
drags a bit of transversalis fascia
femoral vessels from lateral to medial (NAVEL)
nerve (femoral) artery (ext. illiac --> femoral) vein (ext. illiac --> femoral) empty space with lymphatics
femoral sheath
trasversalis fascia that ensheathes structures as they continue into thigh (the one around lymphatics prone to herniation)
why are femoral hernias more common in females?
wider hips –> larger gap
boundaries that can strangulate a femoral hernia:
inguinal ligament
lacunar ligament
pectineal ligament
direct inguinal hernia
commonly w/in the inguinal triangle below conjoint tendon
indirect inguinal hernia
passes obliquely through the deep inguinal ring –> inguinal canal –> superficial inguinal ring
what two tissues are within the inguinal triangle?
parietal peritoneum + transversalis fascia
