EXAM 3 Flashcards
(30 cards)
The cardinal ligament houses which structures?
Uterine artery and vein
What is the purpose of the Ovarian Ligament?
Attaches the ovary to the uterus
The infundibular/suspensory ligament houses which structures?
Ovarian artery and vein
Name the 3 mesothelial layers of the Broad Ligament.
Mesovarium
Mesosalpinx
Mesometrium
What is the purpose of the Mesometrium layer?
What is special about this layer’s size?
Double peritoneum that surrounds the uterus.
It is the largest
What is the purpose of the Mesosalpinx?
Overlies the fallopian tubes (uterine tubes)
What is the purpose of the Mesovarium?
Attaches the ovary to the broad ligament
If the pelvic floor fails, which ligament would support the entirety of the uterus?
Cardinal ligament
Name the borders of the perineum
Pubic symphysis
Ischial tuberosities
Coccyx
Name the external contents of the urogenital triangle in a female.
Vagina
Urethra
Name the external contents of the anal triangle.
Anus
In the male and female, which two muscles are important for surrounding genital tissue that fills with blood during sexual arousal.
Bulbospongiosum - covers bulb of vestibule
Ischiocavernosum - covers corpus cavernosum
The perineal body is the fibrous attachment site for which muscles.
Levator ani
Superficial transverse perineal
External anal sphincter
The Deep Perineal Space encapsulates which structure in the pelvis.
Urogenital (UG) Diaphragm
The UG Diaphragm is composed of which structures.
External urethral sphincter
Deep transverse perineal muscle
The “bowl on a shelf” analogy is referring to the relative layers of which structures in the perineum.
Levator ani (pelvic diaphragm) is the “bowl” that sits within/on the UG Diaphragm “shelf”
UG Diaphragm is superficial to the Pelvic Diaphragm
What structures can be found within the Superficial Perineal Space
Mostly fat
Neurovascular bundles
Which deep fascia covers the inner layer of the penile shaft
Buck’s Fascia
These continuations of fascia surround the penis and scrotum
Scarpa’s Fascia –> Colles Fascia –> Dartos Fascia
If the urethra and Buck’s Fascia are compromised/ruptured, what can occur?
Urine will leak/extravasate from urethra into the superficial space of the perineum –> from umbilicus to thigh
If the urethra is ruptured but Buck’s Fascia is intact, what can occur?
Urine will extravasate from the ureter and accumulate in the deep space that surrounds the penis
In order to anesthetize the skeletal muscle, skin, and sensation of the female perineum, what procedure can be done?
Transvaginal Pudendal Nerve Block
Describe the course of the Pudendal Nerve once it leaves the sacrum
From S2-S4 the nerve exits the greater sciatic foramen, travels around the sacrospinous ligament, enters the lesser sciatic foramen and branches to innervate perineum
In males, why is a Transperineal Biopsy of the prostate so painful?
Pelvic floor is innervated by highly sensitive autonomic nerves
