A7 ; GU System Flashcards
function of the kidney
electrolyte & fluid balance
filter the blood
which nodes drain lymph from kidneys
para-aortic
drainage of gonad veins ; L&R
R; IVC
L; renal vein first
nerve fibres travelling to bladder always
pelvic splanchnic nerves
which kidney is more inferiorly located
R kidney
epithelial lining of ureter
transitional epithelium ; stratified columnar ?
bladder
- male; recto vesicle pouch ?
- female ; vesico & recto pouch ;
- pouch between the bladder & rectum
- females ; VESICO; extension of peritoneal cavity and anterior wall of uterus
RECTO -uterine ; extension of PC and post Wall of uterus
Structures touching the kidneys - anterior and posterior
posteriorly; look at diagram in workbook
- psoas major
- quadratus lumborum
- aponeurosis of transverses abdominis
ribs 11 & 12 but just rib 12 for right kidney as its more inferior
anteriorly ;
RHS; liver, duodenum, transverse colon ; hepatic flexure
LHS; stomach, spleen, tail of pancreas (right in middle), jejunum & splenic flexure
hilum of kidney ; order of structures there from anteroposteriorly (front to back)
VAP; renal vein, artery , pelvis
by what mechanism are the contents of the ureter transferred
peristalsis
when are the ureters narrowest
whats the clinical significance of these narrowings
- uteropelvic junction
- pelvic brim
- when ureter enters the bladder
CS; this is where a stone is most likely to get trapped
anterior & posterior relations to bladder in males and females
EPitheliAL lining of bladder
MALE
Ant; pubic symphysis
post; anus
FEMALE
Ant; pubic symphysis
post; uterus, vagina, cervix - VULVA ?
- transitional epithelium ; stratified columnar epithelium
bladder
- muscles name them
detrusor
internal sphincter
external sphincter - VOLUNTARY
EXPLAIN why urination occurs or doesn’t occur using the muscles of the bladder
Urination;
- detrusor CONTRACTS to push all the urine out
- internal sphincter relaxes but at this stage EXTERNAL SPHINCTER is still constricted
occurs by PARASYMPATHETIC INNERVATION
- somatic motor innervation needed for ES to open
- Ach travels down puedenal nerve - binds to a nicotinic receptor and the ES relaxes ; urine can flow
NO URINATION ; RETENTION
- detrusOR muscle relaxes and so it can hold a lot of urine
- internal spincter contracts - no urine can flow
- occurs by SYMPATHETIC innervation
in a male what lies between the internal and external sphincter muscles
PROSTATE GLAND
MALE urethra
- preprostatic
- prostatic
- membranous or intermediate
- spongy/penile
pubic symphysis is what type of joint
secondary cartilaginous or symphysis
