Q

what’s the bladder trigone

A
  • 2 ureteric orifices on either side of the ureteric meatus that pump pee into the bladder
  • the back wall of the bladder is what prevents the urine from being piped back into the ureter

Q

how are the male and female bladders different?

21
Q

where is the prostate located

A

right under the bladder of males

22
Q

what are the four urethras in males?

A 
preprostatic urethra
(then internal sphincter)
prostatic (prostate) urethra
(external sphincter)
membranous urethra
spongy urethra
23
Q

where is a kidney stone most likely to get stuck in a male urethra?

A

-in the membranous urethra because it’s the most narrow part (prostatic urethra is the widest)

24
Q

what are some components of the prostate?

A
  • urethral crest -bump inside
  • seminal colliculus- bump
  • prostatic ducts- provide nutrients to semen
  • prostatic utricle -remnant
  • ejaculatory ducts x2
25
Q

fxn of bladder

A

reservoir for pee

26
Q

what is the difference between adult and child bladder

A

child often rests in abdomen

27
Q

detrusor muscle

A

bladder muscle that lies at the posterior wall that prevents urine from going back up the ureter

28
Q

what’s different between male and female urethral necks?

A

Female neck muscle is same as the urethral muscle (voluntary)
-Male- urethral neck is continuous with prostatic muscle (involuntary) to create internal sphincter to prevent semen from entering bladder

29
Q

urethra vs ureter

A

ureter- tx pee from kidneys to bladder

urethra- tx urine from bladder to outside

30
Q

how are urethras different between males and females?

A

females have one and goes anterior to vagina

males have 4- preprostatic, prostatic, membranous and spongy urethra

31
Q

describe preprostatic, prostatic, membranous and spongy urethra and where are the internal and external sphincters

A 
preprostatic- before prostate 
(internal sphincter)
prostatic
(external sphincter)
membranous
spongy
32
Q

path of an egg

A

ovary to infundibulum to ovarian tube that goes- ampulla to isthmus to uterine horn to uterus

33
Q

part of uterus

A

body, fundus, cervix

34
Q

ovarian ligament

A

ovary to uterus (fallopian tube)

35
Q

round ligament

A

uterus to labia majora via inguinal canal

36
Q

mesoovarium
mesosalpinx
mesometrium

A

mesoovarium- suspends ovary
mesosalpinx- suspends uterine tube
mesometrium- suspends uterus

37
Q

innervation of vagina

A

lower 1/4- somatic (deep perineal branch of pudendal)

upper 3/4- autonomic

38
Q

when sperm is made in the testes, it is stored in the epididymis and then exits via the vas deferens. what happens next?

A
  • vas deferens joins with 2 seminal vesicles forming the ejaculatory duct
  • they then converge on the seminal colliculus which is in the extension of the urethral crest
39
Q

bulbourethral glands
what do they do
where do they open to

A

secrete fluid at sexual arousal

open to spongy urethrain BULB of penis

40
Q

semen is a combo of secretions of

A

tests, seminal vesicles, porstate and bulbourethral glands

41
Q

Benign prostatic hyperplasia (hypertrophy), how it’s fixed and complications

A
  • benign prostatic hyperplasia is an increase in size of one part of the prostate that gives extreme urgency to urinate.
  • TURP- used to fix it via intering electric catheter in and obliterating that section
  • complications: mess with internal or external sphincter causing dribbling of urine or sperm entering bladder
42
Q

retropubic space

A

behind pubis- promotes bladder distention

43
Q

retrorectal space

A

behind rectum and accommodates rectum expansion

44
Q

retrovesicle space

A

behind bladder/prostate and rectum
ONLY IN MALE BECAUSE FEMALE HAS THE UTERUS THERE
-allows for expansion of bladder and rectum

45
Q

rectrovesicle pouch

A

-pouch between the bladder, prostate and rectum in MALES

46
Q

rectouterine pouch

vesouterine pouch

A
  • between uterus and rectum (pouch of douglus- deeper than vesouterine pouch)
  • between bladder and uterus
47
Q

spinal level of pudendal nerve

A

s2-4
exits pelvis via greater sciatic foramen, enters perineum via lesser sciatic foramen
supplies skin and muscles of perineum and main sensory nerve for external genitalia

48
Q

spinal level of sciatic nerve

what it does

A

L4-S3
supplies lower limb
exits pelvis via greater sciatic foramen

49
Q

superior gluteal

A

L4-S1
exits pelvis via greater sciatic foramen
supplies gluteus medius, tensor facia lata and gluteus minimus

50
Q

inferior gluteal

A

L5-S2
exits pelvis via greater sciatic foramen
supplies gluteus maximus
