PAS 407- Perineum UPDATED ACTUAL Questions and CORRECT Answers
What is the pelvic diaphragm? structure that separates the pelvic cavity and perineum
diamond
anterior apex: pubic symphysis
posterior apex: tip of coccyx
bilateral apices: ischial tuberosities
What is the shape of the perineum anterolateral: ischiopubic rami
posterolateral: sacrotuberous ligaments
What are the boundaries of the perineum?
anterior portion of the perineum
What is the urogenital triangle?
allows passage of urethra and vagina
What does it allow?
divided into subcutaneous perineal fascia, superficial per-
How is it divided?
ineal pouch, and deep perineal pouch
tough, fibrous connective tissue serving as anchor point
What is the perineal body? for many perineal muscles
Where is it located? located at central point of diamond; midpoint between
ischial tuberosities
What might happen if it were damaged?
prolapse of pelvic organs
superficial fascia that extends from anterolateral abdomi-
What is the subcutaneous perineal fascia?
nal wall to cover urogenital triangle
What is it made up of?
subcutaneous fatty tissue and perineal fascia
, continuation of Camper's fascia from abdominal wall
continues into anal triangle as ischioanal fat pad
What is the subcutaneous fatty tissue a continuation of (in
the urogenital triangle)?
males: disappears in scrotum to facilitate evaporative cool-
ing
What does it continue as?
females: forms mons pubis
How does it differ between males and females?
membranous layer of connective tissue just deep to sub-
cutaneous fat tissue
What is the perineal fascia/Colle's fascia?
continuation of Scarpa's fascia from abdomen; continues
What is it a continuation of? What does it continue as? as fascia lata in thigh
What does it form? forms superficial covering for urogenital triangle
mostly empty intermediate space between subcutaneous
perineal fascia and deep perineal pouch
What is the superficial perineal pouch?
1) superficial transverse perineal muscle
What muscles are found here?
2) ischiocavernosus muscle
3) bulbospongiosus muscle
What muscle forms the posterior boundary of the urogen-

ital triangle?
