13

This connects the 2 pubic bones

pubic sympthysis

14

This is located between the sacrum and ilium anteriorly

anterior sacroiliac ligament

15

This is located between the sacrum and ilium posteriorly

posterior sacroiliac ligament

16

This is located from the ischial spine to the sacrum/coccyx, in the lower boundary of greater sciatic foramen

sacrospinous ligament

17

This is located from the sacrum to the tuberosity of the isichium, in the lower border of lesser sciatic foramen

sacrotuberous ligament

18

This closes off obturator foramen (lower border of obturator canal)

obturator membrane

19

This is a diamond shaped region between the thigh; contains 2 triangles

perineum

20

This triangle involves the passage of urinary and genital

urogenital triangle

21

This triangle involves the passage of rectum and anus

anal triangle

22

This triangle is deep to perineal muscle or UG diaphragm

urogenital triangle

23

This triangle is in the plevic floor muscles or pelvic diaphragm

anal triangle

24

This structure is the joining of the urogenital and anal triangles

pineal body

25

What are the two main muscles of the pelvic diaphragm

levator ani
coccygeus

26

What are the three bands that make up the levator ani

iliococcygeus
pubococcygeus
pubrorectalis

27

What muscles assist those of the pelvic diaphragm

piriformis
obturator internus

28

This muscle extends from anterior sacrum to greater trochanter, passing behind greater sciatic notch, and closes off posterior/superior pelvic outlet

piriformis muscle

29

This muscle extends from obturator foramen to greater trochanter, covered with thick fascia and attaches to legator ahi as tendinous arch

obturator internus

30

This is anterior/inferior to pelvic diaphragm extending between 2 pubic arches and attaching posteriorly to perineal body

urogenital diaphragm

31

The UG diaphragm is composed of what muscles and blends with which muscles

composed of deep transverse perineal body
blends with sphincter muscles of urethra (and vagina in females)

32

These transport urine from kidneys to bladder, cross external iliac vessels and descend into pelvis

ureters

33

True or False
The ureters travel to posterolateral aspect of urinary bladder

True

34

This stores urine prior to expulsion through urethra and is covered with peritoneum and supported by pelvic floor

urinary bladder

35

What is the muscle that makes up the urinary bladder

smooth muscle; detrusor urinae

36

The urethra is how long in women and located where

3.5-4cm
between bladder and external urethral orifice

37

Which is longer, the male or female urethra

male

38

What are the four parts of the male urethra starting closest to the bladder

preprostatic
prostatic
membranous
spongy

39

This is located in true pelvis superior to pelvic floor

rectum

40

The rectum is normally constricted by what

puborctal sling; made up of puborectalis muscle

41

This emerges in anal triangle inferior to pelvic floor and is continuous with rectum at anorectal junction at puborectal sling

anal canal

42

The puborectal sling produces curvature at what and when relaxed allows what

curvature at anorectal junction
relaxes to allow defecation

43

What are the two main components of the male pelvic viscera

ductus (vans) deferens
reproductive glands

44

What are the three reproductive glands of the male pelvic viscera

seminal vesicles
prostate gland
bulbourethral (Cowper's) gland

45

This joins the vas deferens forming the ejaculatory ducts, emptying into prostatic urethra

seminal vesicles

46

This is a walnut sized gland between the bladder and UG diaphragm

prostate gland

47

These are 2 pea sized glands within UG diaphragm, emptying into penile urethra
