Session 27 - Pelvic Organs and Female External Genitalia Flashcards
Why may inflammation of the ovary may cause pain along the medial aspect of the
thigh?
Ovary sits near the obturator nerve
Obturator nerve innervates the skin of the medial thigh
What is a retroverted uterus?
When the uterus tits towards the rectum or sacrum
What maintains the normal position of the uterus?
Levator ani muscles
Cervical ligaments
Broad ligaments
To which lymph nodes would cervical cancer spread?
Cervix bs is the int iliac arteries
So lymph nodes alongside these arteries
What’s the blood supply to the cervix?
Internal iliac arteries
What structures may be palpable during examination through the vagina?
Ant
Lat
Post
Ant - Base of bladder and urethra
Lat - Ureter, levator ani
Post - rectum, rectourerine pouch, perineal body
Why is the ureter in danger of being damaged during a hysterectomy (removal of the
uterus)?
The ureter runs immediately under the uterine artery which is ligated during
hysterectomy (‘water under the bridge’). Care must be taken not to injure or
ligate the ureter.
What feature stops urine passing back up the ureter to the kidney when bladder
pressure is high during urination?
The ureter passes through the bladder wall obliquely forming a flap valve. This
prevents the reflux of urine into the ureter.
Where does the bladder lie when full?
Fundus of the bladder lies immediately above the pubis symphysis
A 25 year old woman involved in a car crash suffered complete transection of her spinal
cord at the level of T6. Do you think she is able to tell when her bladder is full? Does her
bladder empty via muscle contraction or does it simply “overflow”?
No sensation a possibility
Inhibitory impulses from the brain cannot reach the bladder
Micturition (auto reflex that causes detrusor muscle to contract) is initiated and cannot be suppressed
