Answer 1

right kidney

Question 2

renal hilus

Answer 2

indentation/physical part of the kidney

Question 3

renal sinus

Answer 3

the space where arterys and nerves enter the kidney, usually asssociated with fat

Question 4

Which species have multilobar kidneys?

Answer 4

bovine and ruminant

Question 5

What makes a kidney unlobar or multilobar?

Answer 5

arrangement of the medulla

Question 6

renal papilla

Answer 6

apex of the renal pyramids, contain the end of the paillary ducts

Question 7

renal crest

Answer 7

the fusion of the renal papillae in unilobar kidneys to make a single papilla

Question 8

pssuedopyramidal kidneys

Answer 8

carnivores and small ruminants have pelvic recesses as a remnant of development

Question 9

what species doesn’t have a renal pelvis and what do they have instead

Answer 9

bovine have minor and major calyx/calyces

Question 10

equine kidney

Answer 10

renal pelvis wwith central cavity and terminal recesses that go towards the poles of the kidneys

Question 11

terminal recesses

Answer 11

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

Question 12

pig kidney

Answer 12

renal peelvis and calyces

Question 13

calyx

Answer 13

cup-like expansions of the ureter/renal pelvis

Question 14

blood supply to kidneys

Answer 14

renal –> segmental –> interlobar –> arcuate –> interlobular –> cortical/peritubular capillaries

Question 15

capsular veins

Answer 15

ONLY present in cats, run along grooves in the renal surface and drains the capsule into the renal vein

Question 16

are capsular and subcapsular arteries the same?

Answer 16

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

Question 17

ureteric osteum

Answer 17

opening of ureter into dorsal surface of the urinary bladder

Question 18

rugae

Answer 18

folds in the bladder that disappear when distended

Question 19

Trigone of the urinary bladder

Answer 19

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

Question 20

detrusor muscles

Answer 20

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

Question 21

urethralis m.

Answer 21

sstriated/voluntary muscle around the pelvic urethra

Question 22

umbilical cord

Answer 22

umbilical vein, umbilical arteries, urachus

Question 23

urachus

Answer 23

connects allantoic sac to urinary bladder

Question 24

What artery commonly stays patent in ruminants?

Answer 24

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

Question 25

patent urachus potential problems

Answer 25

“navel ill,” urachal infectiions, omphalophlebitis (leads to sepsis)

Question 26

In which sex is the urethra subdivided into parts?

Answer 26

the male - pelvic and penile portions

Question 27

colliculus seminalis

Answer 27

in the pelvic portion of the urethra, the little bump between the prostate

Question 28

urethral crest

Answer 28

just prior to the colliculus seminalis in the pelvic urethra
