Q

terminal recesses

A

present in the equine kidney andhave muscous glands that secrete mucin and gives horse urine a cloudy/turbid appearance (albuminuria)

16
Q

are capsular and subcapsular arteries the same?

A

NO, all specieis have subcapsular (drain to interlobular veins)

17
Q

ureteric osteum

A

opening of ureter into dorsal surface of the urinary bladder

18
Q

rugae

A

folds in the bladder that disappear when distended

19
Q

Trigone of the urinary bladder

A

around the neck of the bladder, bordered by ureteric orifices and the internal urethral orifice (urethral crest in males)

20
Q

detrusor muscles

A

3 smooth musscle layers of bladder wall (the middle layer is circular)

21
Q

urethralis m.

A

sstriated/voluntary muscle around the pelvic urethra

22
Q

umbilical cord

A

umbilical vein, umbilical arteries, urachus

23
Q

urachus

A

connects allantoic sac to urinary bladder

24
Q

What artery commonly stays patent in ruminants?

A

umbilical/cranial vesical artery (instead of becoming round ligament of the bladder)

25
patent urachus potential problems
"navel ill," urachal infectiions, omphalophlebitis (leads to sepsis)
26
In which sex is the urethra subdivided into parts?
the male - pelvic and penile portions
27
colliculus seminalis
in the pelvic portion of the urethra, the little bump between the prostate
28
urethral crest
just prior to the colliculus seminalis in the pelvic urethra
