Q

What is caused by early splitting of the ureteric bud?

A

duplication of ureter

33
Q

Does partial splitting or complete splitting of the ureter ever occur?

A

yes

34
Q

The earlier the splitting occurs, the more likely you will get (blank) split which is much more severe

A

complete

35
Q

What is an ectopic ureter opening?

ureter connected to inappropriate area

36
Q

With growht, (blank) ascends and (blank) descends

A

kidney, gonads

37
Q

Initially you have only one entry into the cloacal what is it?

A

mesonephric duct

38
Q

As the metanephric duct forms and grows what happens to the mesonephric system?

majority of it degenerates with some remnants in contact with the gonad remaining

39
Q

the (blank) of the urogenital sinus will form the prostate

A

mesenchyme

40
Q

What is the ascent of the kidney caused by?

A

decreased body curvature and by growth of the body in the lumbar and sacral regions

41

pelvis

42
Q

If kidney fuse and get stuck on inferior mesenteric artery, what arises?

A

a horshoe kidney

43
Q

If you have a horseshoe kidney what will it get stuck on?

Cloaca

45
Q

Cloaca divides into urogenital sinus (anterior) and the anal canal (posterior) by (blank) septum.

A

urorectal

46
Q

What is the structural opening of the urinary, intestinal and reproductive systems

A

pelvic part

50
Q

What part of the urogenital sinus differs between two sexes?

lower phallic part (penile urethra, female urethra)

51
Q

What does the urogenital sinus turn into?

A

urinary bladder and definitive sinus

52
Q

Where are the mesonephric ducts absorbed?

A

into the bladder wall

53
Q

Mesonephric ducts are absorbed into the bladder wall, off of the mesonephric ducts the (blank) forms. Then the ureter then moves and enters the (blank) separately.

A

ureter

bladder

54
Q

Which direction does the newly formed ureter travel?

A

cranially

55
Q

(blank) move lower to enter urethra where prostate forms and ducts become ejaculatory ducts in males.

mesonpehric ducts

56
Q

parts of ducts incorporated in bladder forms (blank) area of the bladder

A

trigone

57
Q

Both mesonephric ducts and ureters originate from the (blank)

A

mesoderm

58

A

mesodermal

59
Q

With times, the mesodermal lining of the trigone is replaced by (blank)

A

endodermal epithelium

60
Q

What are three major bladder defects?

urachal fistula
exstrophy of the bladder
epispadias

61
Q

What is a the remnant of a short term connection from the bladder to the umbilicus?

Urcharus or old allantois

62
Q

What is the old allantois/urachus of the bladder to umbilicus specifically named?

A

the median umbilical ligament

63
Q

What happens if the allantois of the uracha persists?

A

a urachal fistula forms

64
Q

What is it called if only a local area of of allantois persists resulting in cystic dilation?

A

urachal cyst

65
Q

What is it called if the upper part of the allantois persists?

A

urachal sinus

66
Q

What is a sign of urachal fistula??

A

urine drains from umbilicus

67
Q

(blank) is a malformation in which the urethra opens on the dorsum of the penis; frequently associated with exstrophy of the bladder.

A

Epispadias

68
Q

What is a constant feature of exstrophy of the bladder?

A

epispadias

69
Q

What is exstrophy of the bladder?

A

it is a ventral body wall defect where the bladder mucosa is exposed

70
Q

A lack of mesodermal migration into the region between the umbilicus and genital tubercle, followed by rupture of the thin layer of ectoderm results in what?

A

exstrophy of the bladder
