Lower Urinary Tract Anatomy Flashcards
what blood vessel can be used to locate the adrenal gland
phrenicoabdominal vein/artery
what does the phrenicoabdominal vein/artery supply/drain
the body wall and diaphragm
where are the adrenal glands located
cranial to the kidneys
what blood vessels supply the sub-lumbar/hypaxial muscles
deep circumflex iliac vein/artery
where does the peritoneum connect to the kidneys
ventral aspect only
where does the retroperitoneal space connect to
mediastinum
renal crest
fused pyramids in unilobar kidneys; drains into the renal pelvis
renal pelvis
dilation of the ureter that collects urine from papillary ducts
renal sinus
holds the renal pelvis and surrounding fat
what species have a unilobar kidney
dogs, cats, horses
drainage from unilobar kidneys
renal crest –> papillary ducts –> pelvis
NO CALYCES
what type of kidneys do pigs have
multilobar, smooth
drainage from multilobar, smooth kidneys
minor calyx –> papillary ducts –> renal pelvis
what species has external lobes on kidneys
bovine
drainage from a multilobar, lobulated kidney
minor calyx –> papillary ducts –> major calyx (2)
what is unique about feline kidneys
capsular veins surround renal parenchyma
what is unique about horse kidneys
has two elongations of the renal pelvis called terminal recesses
has a very large number of papillary ducts that drain into the pelvis
ureteral orifice
openings of the ureters into the bladder
located on dorsal aspect of the bladder at the trigone
trigone
area of the caudal-dorsal surface of the bladder that contains the two ureteral orifices and the narrowed neck of the bladder
terminal aorta
the end of the aorta that splits into 3 branches
umbilical artery
(L and R) one of the three branches of the terminal aorta that supplies the bladder
species differences in umbilical artery
50% of dogs - umbilical artery turns into round ligament of the bladder
other 50% of dogs - continues carrying blood and remains as umbilical artery
ruminants - persists as umbilical artery (very large in calves); can branch in some females to supply the uterus
where is the prostate located
dorsally at the neck of the bladder
genital fold
ligament in males that is located between the ductus deferens on the dorsal aspect of the bladder
urethral tubercle
exit of the urethra into the vestibule
located cranial to the external genitalia
suburethral diverticulum
blind sac located ventrally to the opening of the urethra
ONLY in bovine and pigs
order of openings in the female vestibule
vagina (dorsal)
urethra
clitoral fossa (ventral; blind sac)
