anatomy Flashcards
anterior sacroiliac joint
synovial
posterior sacroiliac joint
fibrous
pubic symphysis
secondary cartlaginous
most lateral muscle in pelvis
obturator internus
bartholins gland
in superficial pouch
male xx gland
deep pouch
crura is made of what
erectile tissue
other muscles in urogenital triangle
ischiocavernosus and bulbospongiosus
also superficial transvesre muscle
nerve supply to perineum
pudendal
lymph drainage of fallopian tube/ovary/fundus of uterus
para aortic L2
body of the uterus lymph drainage
external iliac
perineal lymph drainage
superficial inguinal
the internal iliac artery becomes what
the anterior and posterior branch
inferior cesicle/uterine nerves ar branches of what
the anterior branch of the internal iliac artery
testes lymph drainage
para aortic
contents of the epidural space
fat and veins
external iliac and internal iliac come from what
common iliac
which artery lies underneath the inguinal canal
femoral
station if negative
head is above the ischial spines
AP or transverse bigger or smaller at pelvic outlet
AP is bigger - hence rotation to OA
Perineum
shallow space between the pelvic diaphragm and skin
levator ani supply
S3,4,5 - nerve of levator ani
will be deep if inferior view
wont see a vagina
Perineal body
collagenous and elastic where perineal muscles attach
bartholins gland
dot at the end of the crura
touching peritoneum supply
visceral afferent
sYmpathetic
T11-L2
suprapubic
not touching the peritoneum supply
visceral afferent
parasympathetic
S2,3,4
Below levator ani supply
S2,3,4
Pudendal nerve
Somatic sensory
pain localised to the perineum
supply to a structure crossing the perineum e.g. urethra or vagina
visceral afferent
parasypathetic
S2,3,4
Subarachnoid space ends at
L2
spinal anaesthesia/epidural will result in
sympathetic blockade below level
vasodilation
postural hypotension
pudenal canal contains
pudendal nerve
artery
vein
post re-entry to lesser sciatic foramen (by looping behind the sacrospinous lig)
pelvic diaphragm
levator ani and coccygeus
below pelvic diaphragm is
deep perineal pouch
deep perineal pouch contains
urethra (and vag), bulbourethral glands in males, nevb for penis/clit, an extension of ischioanal fat pads
and
deep transverse perineal muscle, compressor urethrae
superficial to deep perineal pouch
perineal membrane
superificial perineal pouch in males contains what
bulb - CS, CRURA - CC
associates with bulbospongiosus and ischiocavernosus
