3.4.3. ANATOMY LAB Female Anatomy Flashcards
Retropubic space (of Retzius)
Retropubic space is the extraperitoneal space between the pubic symphysis and urinary bladder.
How can we use the retropubic space in surgery?
This avascular (without blood vessels) space permits a relatively quick and bloodless surgical access to the bladder for drainage of urine (for example, if the normal urethra has been damaged and cannot be used to drain the urine)
Rectouterine pouch (cul-de-sac) of Douglas
the extension of the peritoneal cavity between the rectum and the posterior wall of the uterus in the female human body.
Two most prone areas to infection
Rectouterine pouch (cul-de-sac) of Douglas Rectovesical pouch
Culdocentesis
Culdocentesis - Remove the fluid accumulated in the pouch of Douglas
Vesicouterine pouch
is a second, but shallower, pouch formed from the peritoneum over the uterus and bladder, continued over the intestinal surface and fundus of the uterus onto its vesical surface, which it covers as far as the junction of the body and cervix uteri, and then to the bladder.
Also termed Dunn’s pouch, this is an important anatomical landmark for chronic endometriosis
Vesicouterine pouch
Rectovesical pouch
Between the rectum and the bladder the peritoneal cavity forms, in the male, a pouch, the rectovesical excavation (‘rectovesical pouch), the bottom of which is slightly below the level of the upper ends of the seminal vesicles—i. e., about 7.5 cm. from the orifice of the anus.
A membranous partition called the ____ ____ is located at the lowest part of the rectovesical pouch
A membranous partition called the Rectoprostatic fascia (Denonvillier’s fascia) is located at the lowest part of the rectovesical pouch
What is an ectopic pregnancy?
A pregnancy in which the baby and placenta are located and develop outside of the uterus
What is an ectopic tubal pregnancy?
Pregnancy in the fallopian tube
Bicornuate uterus
A bicornuate uterus or bicornate uterus, commonly referred to as a “heart-shaped” uterus, is a uterus composed of two “horns” separated by a septum. In humans, a bicornuate uterus is a type of uterine malformation, but in some other mammalian species, including rodents and pigs, it is normal.
Layers of the uterus
Endometrium, myometrium, perimetrium
Layer of the uterus that cycles during menstruation
Endometrium
Discuss Anteversion and anteflexion
Normally the uterus lies in anteversion & anteflexion. In most women, the long axis of the uterus is bent forward on the long axis of the vagina. This position is referred to as anteversion of the uterus.
Furthermore, the long axis of the body of the uterus is bent forward at the level of the internal os with the long axis of the cervix. This position is termed anteflexion of the uterus.
Discuss retroverted uterus
About one quarter of women have a retroverted uterus. This means the uterus is tipped backwards so that its fundus is aimed toward the rectum.
This type of uterus increases the chance of having a prolapse
Retroverted uterus
What is a uterine prolapse
Uterine prolapse is a protrusion of the uterus into the vagina
What is a vaginal fistula and how does it arise?
A vaginal fistula starts with some kind of tissue damage. After days to years of tissue breakdown, a fistula opens up.
A fistula is a passage or hole that has formed between:Two organs in your body or an organ in your body and your skin.
Epiosotomy
Episiotomy - An episiotomy is a surgical cut in the muscular area between the vagina and the anus (the area called the perineum) made just before delivery to enlarge your vaginal opening
Within the cardinal ligaments are the ____ ____. There are also important lymph nodes here, which can not be palpated unless ______________.
Within the cardinal ligaments are the uterine arteries. There are also important lymph nodes here, which can not be palpated unless there is cancer
Describe what happens to the uterus with aging
Uterus with aging - With aging, there is a decrease in the amount of muscle and connective tissue, including that in muscles, ligaments, and other tissues that support the bladder, uterus, vagina, and rectum. As a result, the affected organs may sag or drop down (prolapse), sometimes causing a feeling of pelvic pressure or fullness, difficulty urinating, loss of control of urination or bowel movements (incontinence), or pain during sexual intercourse.
Ureters pass beneath the ______ _____ and the _____ _____.
Ureters pass beneath the uterine arteries and veins
The ____ ____ ____ supplies proper blood flow to the vagina, uterine tube, uterus, uterine ligaments, and the ovaries
The Uterine artery plexus supplies proper blood flow to the vagina, uterine tube, uterus, uterine ligaments, and the ovaries
Trace the uterine artery
The uterine artery connects to the internal iliac artery at the top. It moves down along the uterus, moving across the ureter anteriorly. The artery then wraps around the cardinal ligament, or main ligament of the uterus, and ends at the uterus itself.
Parametrium
The parametrium is a band of tissue, dividing the bladder from the cervix and the artery moves through this area.
Pap Smear
Pap Smear - A Pap smear, also called a Pap test, is a procedure to test for cervical cancer in women. A Pap smear involves collecting cells from your cervix — the lower, narrow end of your uterus that’s at the top of your vagina
Hysterectomy vs. Vaginal hysterectomy?
Hysterectomy - Removing the uterus
Vaginal hysterectomy - remove the uterus through the vagina
Pudendal Block
Pudendal block - The pudendal block gets its name because a local anesthetic such as, lidocaine or chloroprocaine, is injected into the pudendal canal where the pudendal nerve is located. This allows quick pain relief to the perineum, vulva, and vagina. A pudendal block is usually given in the second stage of labor just before delivery of the baby.
Discuss the differences between the male and female urethra
The female urethra is much shorter than the male counterpart, and its opening is situated between a woman’s clitoris and vagina.
Why are women more prone to infection?
Prone to infections because women have a shorter urethra than men do, which cuts down on the distance that bacteria must travel to reach a woman’s bladder.
Ischio cavernosus action and innervation
Action - Assist the bulbospongiosus
Innervation - pudendal nerve
Bulbospongiosus action and innervation
Action - Clenches vagina
Nerve - Pudendal
Internal pudendal artery supplies what
Internal pudendal artery - Branches to the clitoris and labia
What does the ilioinguinal nerve supply?
Ilioinguinal nerve - Skin over the root of the penis and upper part of the scrotum (male), skin covering the mons pubis and labium majus (female)
Genitofemoral nerve - Innervates what?
Genitofemoral nerve - Innervates cremaster muscle
