Day of Exam Flashcards
diaphragm innervation
phrenic nerve C3-C5
IAO innervation
ilioinguinal and iliohypogastric n
EAO attachments
lower 8 ribs –> iliac crest, rectus sheath
IAO attachments
TFL –> iliac crest, rectus sheath, inguinal lig
TA attachments
costal cartilages, TFL –> iliac crest, rectus sheath, inguinal lig
greater sciatic notch contents
nerves= pudendal, super and inferior gluteal
muscle = piriformis
vessels = internal pudendal a/v, sup/inf gluteal a
lesser sciatic notch contents
nerve = pudendal
muscle = obturator interus
vessel = internal pudendal a/v
secondarily retroperitoneal organs
pancreas
rectum (upper 2/3)
colon (ascending, descending colon)
duodenum (everything else but superior/1st seg)
what are the 3 abdominal viscera not digestive?
spleen – filters blood
kidney – urinary
suprarenal glands
stomach fxns
HCl disinfects fodo and denatures protein
protease pepsin
makes chyme
small intestine fxns
enzymatic digestion
nutrient absorption
liver fxns
receives blood from GI
detox
glycogen
produces bile
gallbladder
stores and releases bile
pancreas
enzymes
bicarbonate to neutralize
endocrine organ
large intestine fxns
absorbs water and minerals
no DIGESTION
lots of bacteria
IAO segmental innervation
T7-L1
RA segmental inenrvation
T5-T12
TA/EAO segmental innervation
T7-T12
what nerve travels across iliacus?
lateral femoral cutaneous nerve
renal arteries are end arteries – what does this mean?
they never anastomose so if there’s a blockage it results in death of region
kidney sympathetic innervation
least splanchnic n T12 > aorticorenal ganglion (SYNAPSE) > renal plexus > kidney
kidney parasympathetic innerv
vagus n > esophageal plexus > posterior vagal trunk > celiac ganglion > renal plexus > kidney (SYNAPSE)
celiac ganglion is parasymp and symp
celiac ganglion - what does it partake in?
parasympathetic: post vagal trunk > celiac ganglion —-> target: kidney
symp: greater splanchnic nn T5-T9 > celiac ganglion —-> target: foregut
bladder parasymp inner
S2-S4 > pelvic splanchnic > inferior hypogastric plexus > wall bladder (SYNAPSE) contract
bladder symp innerv
T10-12, L1-L2 > lumbar splanchnic > sup/inf hypogastric plexus > inferior hypogastric plexus SYNAPSE > bladder relax
ductus deferens is ___ to ureter
superior
whats the ligament that holds the ovarian vessels?
ovarian suspensory ligament
ligament that holds uterine vessels?
broad ligament (mesosalpinx)
purpose of ischioanal fossa
fat pads prevent prolapse of rectum
erection nerves
parasympathetics
pelvic splanchnic S2-S4 > prostatic plexus > cavernous nerves
sympathetic = strenuous
parasympathetic = paradise
parasymp —> synapse at target
symp —> synapse at ganglion
erection muscles
smooth muscles of corupus cavernosus
ejaculation
sympathetic
lumbar splanchnic L1-L2 > superior and inferior hypogastric plexus
bladdr does what when activated by parasymp
contracts — to release urine bc rest and digest mode (parasymp) means you have time to go to the potty
bladder does what when activated by symp
relaxes — bladder fills up with urine because when you’re scared, there’s no time to use the restroom.
