Female Anatomy Flashcards
What are the layers of the uterus?
Endometrium - glandular
Myometrium - muscle layer, contracts and relaxes (responses to pgs)
Perimetium - serous
Arterys supplying the uterus and ovaries?
Ovaries- Arising from aorta L1
Uterine- internal iliac
Actions of the pelvis floor
Delivery- helps rotation of the presenting part
Continence (puborectalis for faecal) and also urinary
Keeps organs inside
Maintaining effective intra- abdominal pressure
What pH is the vagina?
Acidic PH 3.8-4.4
The uterus is suppose to be mobile, what can you think you that would keep it in a fixed position?
Adhesions by endometriosis or PID
Describe some of the uterine abnormalities
Bicornate (partially divided uterus)
Unicornate (one side fails to develop)
Vaginal Septate
Hypoplasitic
What are the classification types of FGM?
1- removal of the clitoris and or prepuce
2- removal of clitoris and lab minor
3- narrowing of the vaginal orifice using the lab minor or maj, (infibulation)
4- any other harmful process to the genitalia for non-medical purposes (scraping pricking piercing)
What are the different pelvis shapes?
Platypelliod - (African)
Gynaecoid - favourable
What does ‘station 0’ refer to?
Ischial spines
What are the muscles of the pelvic floor?
Levator ani and the coccygeous
Which landmark is used for a pudendal nerve block?
Ischial spines
Pudendal - inervation to perineum. S2-s4.
What structures classify perineal tears 1-4?
1 - vaginal mucosa
2 - vaginal mucosa and perineal body (subcutaneous tissue)
3 - extends to external anal sphincter
4 - through the anal sphincter and rectal mucosa
Whats the function of the different prostaglandins?
PGI and PGE are vasodilator of the uterine arteries. Produced by the myometrium.
PG I2 inhibits platelet aggregation
PG F is a vasoconstrictor
