Kidney and Bladder Flashcards
Which kidney sits more cranial?
right kidney
renal hilus
indentation/physical part of the kidney
renal sinus
the space where arterys and nerves enter the kidney, usually asssociated with fat
Which species have multilobar kidneys?
bovine and ruminant
What makes a kidney unlobar or multilobar?
arrangement of the medulla
renal papilla
apex of the renal pyramids, contain the end of the paillary ducts
renal crest
the fusion of the renal papillae in unilobar kidneys to make a single papilla
pssuedopyramidal kidneys
carnivores and small ruminants have pelvic recesses as a remnant of development
what species doesn’t have a renal pelvis and what do they have instead
bovine have minor and major calyx/calyces
equine kidney
renal pelvis wwith central cavity and terminal recesses that go towards the poles of the kidneys
terminal recesses
present in the equine kidney andhave muscous glands that secrete mucin and gives horse urine a cloudy/turbid appearance (albuminuria)
pig kidney
renal peelvis and calyces
calyx
cup-like expansions of the ureter/renal pelvis
blood supply to kidneys
renal –> segmental –> interlobar –> arcuate –> interlobular –> cortical/peritubular capillaries
capsular veins
ONLY present in cats, run along grooves in the renal surface and drains the capsule into the renal vein
are capsular and subcapsular arteries the same?
NO, all specieis have subcapsular (drain to interlobular veins)
ureteric osteum
opening of ureter into dorsal surface of the urinary bladder
rugae
folds in the bladder that disappear when distended
Trigone of the urinary bladder
around the neck of the bladder, bordered by ureteric orifices and the internal urethral orifice (urethral crest in males)
detrusor muscles
3 smooth musscle layers of bladder wall (the middle layer is circular)
urethralis m.
sstriated/voluntary muscle around the pelvic urethra
umbilical cord
umbilical vein, umbilical arteries, urachus
urachus
connects allantoic sac to urinary bladder
What artery commonly stays patent in ruminants?
umbilical/cranial vesical artery (instead of becoming round ligament of the bladder)
patent urachus potential problems
“navel ill,” urachal infectiions, omphalophlebitis (leads to sepsis)
In which sex is the urethra subdivided into parts?
the male - pelvic and penile portions
colliculus seminalis
in the pelvic portion of the urethra, the little bump between the prostate
urethral crest
just prior to the colliculus seminalis in the pelvic urethra
