test three deck 1 Flashcards
The iliohypogastric nerve is derived from
ventral rami of t12 and l1
what nerve does the iliohypogastric nerve run with?
the ilioguinal nerve
where does the iliohypogastric nerve emerge?
posterior to the kidney
what does the iliohypogastric nerve innervate
interanl oblique and ta motor, posteriorlateral gute and L1 derm, then runs between these muscles
where does the ilioinguinal nerve run?
lateral to psoas and post to kidney, traverses the iliac crest, then pierces ta, int oblique, goes through superficial inguinal ring
does the ilioinguinal nerve go through the inguinal canal?
no, it only runs in the superficial ring, not the deep ring
what does the ilioinguinal nerve innervate
motor internal oblique and ta, sensory to upper medial thigh– scrotum and labia
where does the genitofemoral nerve run?
laterally through psoas, post to ureter
what branch does the genitofemoral nerve belong to?
l1,l2, anterior (ie to psoas)
what devisions of the genitofemoral nerve are there?
genital, and femoral branches
what is the innervation of the lateral femor cutaneous nerve, and where does it run?
l2/l3, lateral to psoas then deep to the inguinal lig
what makes up the femoral nerve?
L2-L4,
what is the sensory area for the femoral nerve?
ant central thigh, and medial shank via saphenous
what is the motor area for the femoral nerve?
quads, iliacus pectineus, sartorius
what is the innervation of obturator, and what category is it?
medial l2-l4
what muscles does obturator innervate
obturator externus, pectineous, adductors long, brev, 1/2 magnus, gracilis
where is the sensory region of obturator?
region medial thigh, also in the acetabulm
what is the largest and strongest ligament in the si joint?
interosseous ligament
two ligaments that resist anterior movement of sacrum
iliolumbar and lumbarsacral
what muscle divides the greater sciatic foramen?
the piriformis
in what landmark is the obturator internus located
the lesser sciatic foramen
name the levator ani muscles
puborectalis, pubococcygeous, iliococcygeous
what is the action of the pubic rectalis muscle?
pulls the angle of the rectum anterior, helping with fecal continence
true or false, the perineal body is essential for function of pelvic floor, rupture can lead to prolapse of rectum
true

the trigone
what is the innervation of muscles of the pelvic floor
pudendal, s2-24,
three “superficial” pelvic muscles, anterior pelvic triangle
bulbospongiousus, ichicavernosus, superficial transverse perinieal
which kidney is lower?
The right kidney is lower than the left
do men have a pubovesial lig?
no, they have a puboprostate lig
