Three layers of the pelvic floor from deep to superficial
Pelvic diaphragm
Muscles of the deep perineal pouch
Perineal membrane
Two main muscles of the pelvic diaphragm
Levator ani
Coccygeus
Three parts of levator ani
Puborectalis
Pubococcygeus
Iliococcygeus
Nerve supply to levator ani
Pudendal nerve
Nerve to levator ani
Additional ligaments which support the pelvic organs
Uterosacral
Transverse cervical (cardinal)
Lateral ligament of bladder
Lateral rectal ligament
Location of the bulbourethral glands
Within the deep perineal pouch
Muscles of the deep perineal pouch
Deep transvere perineal muscle
Compressor urethrae
Last layer of passive support for the pelvic organs
The perineal membrane
Where does the superficial perineal pouch lie?
Below the perineal membrane
Where are the bulb, crura and associated muscles of the penis located?
Superficial perineal pouch
Associated muscles of the penis
Bulbospongiousus and ischiocavernosus
What forms the a) bulb and b) crura of the penis?
a) corpus spongiosum
b) corpus cavernosa
The clitoris and crura are formed by what?
Corpus cavernosum
Where are the vestibular glands located?
Within the superficial perineal pouch below the opening of the vagina
Under what circumstances does the pelvic floor actively contract?
Increase in abdominal pressure e.g. coughing sneezing laughing
