lower part of urethra
vessels and nerves 
bulbourethral glands

Question 2

Superficial perineal fascia continuous with

Answer 2

Campers fascia of abdomen

Question 3

deeper part of superficial perineal fascia continuous with AKA

Answer 3

continuous with Scarpas fascia AKA Colle’s fascia now

Question 4

deepest part of fascia

where is it attached

Answer 4

Dartos fascia

attached to posterior border of UG diaphragm and laterally to ischiopubic rami

Question 5

superficial perineal pouch is made by

Answer 5

colles fascia

inferior fascia of UG diaphragm aka perineal membrane

Question 6

deep perineal pouch is made by

Answer 6

inferior and superior fascia of UG diaphragm

Question 7

contents of superficial perineal space M

Answer 7

Root of penis
muscles
- ischiocarvernosum- 
-bulbospongiosum
-superficial transverse perineal muscle 
central perineal tendon

Question 8

contents of superficial perineal space F

Answer 8

• ischiocarvernosum-
• bulbospongiosum-
• superficial transverse perineal muscle -

Bartholins glands - secrete mucus

Question 9

function of ischiocavernosum M F

Answer 9

Male: cover crura of penis, assists in erection
female: cover crura of clit

Question 10

function of bulbospongiosum M F

Answer 10

male: two halves joined at the midline covering the bulb of the penis at posterior portion of corpus spongiosum
assits in erection and emptying of urethra

female: acts a sphincter for vagina insert into clit

Question 11

function of superficial transverse perineal muscle m/f

Answer 11

From ischial rami to perineal body

Male/ Female: hold and fix central perineal tendon (perineal body) in place

Question 12

Where does the inferior fascia of UG diaphragm fuse***

Answer 12

fuses anteriorly and posteriorly with superior fascia of UG diaphragm

posteriorly* it fuses with posterior border of Colles fascia :WHICH PROVIDES ANTERIOR BOUNDARY FOR THE ISCHIORECTAL FOSSA BELOW THE PERINEAL MEMBRANE

Question 13

where does the posterior fascia of UG diaphragm fuse**

Answer 13

anteriorly and posteriorly with inferior fascia of UG diaphragm

IT FORM THE FLOOR OF THE ANTERIOR SUPERIOR RECESS OF THE ISCHIORECTAL FOSSA*** (BARRIER)

Question 14

contents of male UG diaphragm aka deep perineal pouch

Answer 14

• sphincter urethrae muscle
• deep transverse perineal muscles
• bulbourethral glands
• deep branches of internal pudental vessels
• perineal branches of pudental nerve [ and dorsal nerve of penis]

Question 15

contents of female UG diaphragm aka deep perineal pouch

Answer 15

(muscles-same as male- but less developed )

• sphincter urethrae
• deep transverse perineal muscles
• deep branches of internal pudental vessels
• perineal branches of pudental nerve [dorsal nerve of the clitoris ]

Question 16

branches of internal pudental Male v female

Answer 16

• perineal artery
• artery to bulb of penis/ bulb of vestibule
• deep artery of penis/ clit
• dorsal artery of penis/ clit

Question 17

branches of perineal artery M F

Answer 17

Male: posterior scrotal artery
Female: posterior labial artery

and transverse perineal artery —

Question 18

branches of pudental nerve

Answer 18

perineal nerve
inferior rectal nerve
dorsal nerve to clit/penis

Question 19

what innervates external urethral sphincter

Answer 19

branches of pudental nerve– under voluntary control

Question 20

branch of perineal nerve M /F

Answer 20

M posterior scrotal

F posterior labial?
