What are the hiatuses of the male pelvis?
Urogenital hiatus and anal hiatus
30
What are the four palpable structures of the pelvis?

Urogenital hiatus and anal hiatus. The urogential hiatus will contain the urethra and the vagina
32
What are the superior and inferior boundaries of the perineum?
Pelvic diaphragm is the roof; skin is the floor
33
Using anatomical terms, how is the perineum positioned relative to the pelvic diaphragm in the body?
The perineum is superficial and inferior to the pelvic diaphragm
34
Lithotomy position
Position of patient on their back and opening their legs to reveal the perineum
35
What are the two triangles formed by the palpable structures of the pelvis?
Urogenital triangle and anal triangle
36
What are the three points that define the urogenital triangle?
Public symphysis and left and right ischial tuberosities
37
What are the three points that define the anal triangle?
Tip of coccyx and right and left ischial tuberosities
38
What membrane is found at the anal triangle?
There is none!
39
Urogenital diaphragm
The perineal membrane, found in the front half of the perineum
40
How does the urogenital diaphragm differ in male and female pelvices?
In the female pelvis, the urogenital diaphragm takes up the whole space of the urogenital triangle. In the male pelvis, it is slightly smaller than the triangle
41
In the female pelvis, what are the two openings found in the urogenital hiatus? Which one is more ventral?
Urethra and vagina; urethra is more ventral
42
Ischio-anal fossae
A fossa found between the ischium and the anus, superficial to the pelvic diaphragm and deep to the deep perinal pouch and perineal membrane
43
From superficial to deep, what are the layers found in the urogenital triangle?
Skin -> fatty layer of superficial perineal fascia -> Colle's fascia -> Perineal cleft -> Superficial perineal pouch -> Perineal membrane -> Deep perineal pouch -> ischioanal fossa -> pelvic diaphragm -> Endopelvic fascia -> Peritoneum -> pertioneal cavity
44
From superficial to deep, what are the layers found in the anal triangle?
Skin -> fatty layer of superficial perineal fascia -> Colle's fascia -> Perineal cleft -> Superficial perineal pouch -> ischioanal fossa -> pelvic diaphragm -> Endopelvic fascia -> Peritoneum -> pertioneal cavity There is no peritoneal membrane or deep perineal pouch
45
Deep perineal pouch
A pelvic pouch found above and deep to the perineal membrane
46
Superficial perineal pouch
A pelvic pouch found superficial to perinal membrane and deep to the deep perineal fascia; it contains erectile tissue and associated skeletal muscles
47
What is the difference between the male and female pelvis with regards to the superficial perineal pouch?
Male: trilobar. Female: quadrilobar
48
Perineal cleft
A pelvic cleft found deep to Colle's fascia and superficial to the deep perineal fascia; also known as the subcutaneous perineal pouch
49
Levator ani
The group of muscles that make up the pelvic diaphragm, they lift up the anus
50
What are the muscles that make up the levator ani?
Iliococcygeus, pubococcygeus, puborectalis
51
What are the three bones that make up the pelvic bone?
Ilium, ischium, pubis
52
Ischial spine
A spiny part of the ischium that is the attachment site of the sacrospinous ligament
53
Greater Sciatic foramen
A foramen that is above the ischial spine
54
Lesser Scieatic forament
A forament that is below the ischial spine
55
Sacrospinous ligament
A ligament that runs from the sacrum to the sichial spine
56
Sacrotuberous ligament
A ligament that runs from the sacrum to the ischial tuberosity
57

61
What nerve innervates the obturator internus? What spinal cord segments does it originate from?
"Nerve to obturator internus"; L5 and S1
62

The nerve that innervates the pelvic diaphragm
63
What spinal cord segments does the pudendal nerve originate from?
S2, S3, S4
64
Puborectalis
A muscle that originates from the pubis and wraps around the rectum; it is one of the pelvic diaphragm muscles
65
What nerves innervate the pelvic diaphragm?
Pudendal nerve; S4 directly
66
How do visceral nerves get past the pelvic diaphragm?
They run through the urogenital hiatus
67
How do somatic nerves get past the pevlic diaphragm?
They go around it
68
What nerves and vessels leave the pelvic cavity from above the piriformis?
Superior gluteal
69
What nerves and vessels leave the pelvic cavity from below the piriformis?
Sciatic nerve; post femoral cutaneous nerve; nerve to quadratus femoris; inferior gluteal nerve and vessels; pudendal nerve; nerve to obturator internus
