diapragm kidneys and post abdominal wall Flashcards
(25 cards)
innervation of the diaphragm
phrenic nn supply motor to R and L hemidiaphragms and 30% of sensory to the central portaion of the diaphragm
intercostal nn supply lateral borders and some sensory laterally
what happens if C3-5 get damaged
hemidiaphragm on that side can’t descend (contract) and remains high in the thorax
where are kidneys located
vertebral levels T12-L3
sup pole of L kidney = T11
sup pole of R kidney = T12
what are abnormal kidney attachments
ectopic pelvic = remains ant to sacrum
horseshoe = below IMA
transplanted = in lower abdomen
kidney is encapuslated by….
perirenal fat and renal fascia
path of urine
pyramids (where it's produced) renal papillae minor calyces major calyces renal pelvis ureter
how does vascularization of the kidneys work
R renal a is longer thatn L and passes post to IVC renal aa divide into 5 segments when they reach hilum
L rean v is longer than R and passes ant to aorta
path of ureters
cross psoas maj mm running post to gonadal vessels and ant to ext. iliac a
common ureter abnormalities
bifid renal pelvis/ureter
retrocaval (behind IVC- causes slow drainage and high potential for kidney stones
ureter vascularization
renal a
gonadal a
abdominal aorta
location and shape of adreanal glands
R is triangular and sup to right kidney and post to IVC,
L is semilunar and superomedil to L kidney hear hilum
parts of adrenal glands and their fcns
fibrous capsule (surrounds)
cortex - produces steroids
medulla (center) acts as symp ganglion
sources of suprarenal aa
sup suprarenal aa (6-8) are from inf phrenic a
middle suprarenal aa (1+) are from aorta
inf suprarenal aa (1+) are from renal a
mm of post abd wall
transversus abdominus, quadratus lumborum, psoas maj and minor, diaphragm
how is the post abd wall vascularized
4 paired brs off abd aorta (the lumbar aa) that branch off before bifurcation
subcostal n rami, location and supp
T12, 1 cm above 12th rib
supp sensory to ant/lat abd wall and motor to EO IO TA pyramidalis, RA QL
iliohypogastric and ilioinguinal nn rami, path and supp
L1 desc ant to QL IH runs sup to II and supp supraficial skin of suprabubic region II runs thru inguinal canal and supp it both supp abd mm
genitofemoral n rami, path and supp
L1-L2
pierces psoads maj and desc along it then splits into femoral br medially and ginital br laterally
supp skin inf/ med to inguinal lig and cremaster m of spermatic cord
lateral femoral cutaneous n rami, path and supp
L2 and 3
desc ant to iliacus m and pases deep to inguinal ring
supp ant/lat skin of thigh
femoral n rami path supp
L2-4 runs btwn iliacus and psoas maj deep to inguinal lig and inf to ASIS
supp sensory and motor to ant thigh
obturator n rami path and supp
L2-4 runs medial to psoas maj passing thru obturator for
supp sensory and motor to medial thigh
lumbosacral trunk rami path and supp
L4-5, lg n trunk crosses over ala of sacrum and descends into pelvis to help form sacral plexus
provides general contributions to both plexuses
where do IVC, aorta and esophagus go thru diaphragm?
I 8 10 E A 12
I ate 10 eggs at noon
where are the arcuate ligaments of the diaphragm and what do they represent?
median over aorta
medial over psoas maj/minor
lateral over quadratus lumborum
represent the inf extent of the diaphragm
