Q

Uterine wall layers from superficial to deep

(3)

A
  1. Outer perimetrium-lined by serosa/adventitia
  2. Myometrium
  3. Endometrium-Shed during menses
21
Q

What are the two parts of the endometrium and what do they do?

A
  1. Stratum functionalis-lost monthly if no pregnancy
  2. Stratum basalis: retained during menstruation and provides stem cells for stratum functionalis for next cycle
22
Q

Normal Anatomical Position of Uterus

A
  1. Anteverted
  2. Anteflex
23
Q

What supports the Uterus?

(5)

A
  1. Pelvic floor muscles
  2. Perineal body
  3. Transverse cervical ligaments
  4. Uterosacral ligaments
  5. Round ligaments of the uterus
24
Q

What is Uterine Prolapse?

A
  • Support structures no longer can counteract typical intra-abdominal pressure.
  • Caused by uterosacral ligaments and pelvic floor muscles
24
What are the treatments for Uterine Prolapse?
1. Surgery 2. Exercises 3. Lifestyle changes
25
Epiosotomy procedure
* **Perineal cut** between the vagina and anus w/ surgical scissors d/t breech presentation, large fetus, forceps delivery, fetal distress * Complications include: pain, increased risk of fecal incontinence
26
Blood supply of the uterus | Arterial
1. Uterine arteries-branches of the internal iliac arteries 2. Ovarian arteries-from aorta
27
Venous drainage of the Uterus
Uterine and vaginal veins drain to the **ovarian and internal iliac veins**
28
Hysterectomy
**Removal of the uterus** Indications include: * Uterine fibroids * Pelvic inflammatory disease * Endometriosis * Excessive uterine bleeding * Cancer of the cervix, uterus, or ovaries
29
Cervical Cancer important things to remember
* Detected by **Pap smears** * most are caused by **HPV** (STD) * Main symptom is **abnormal vaginal bleeding**
30
Cervical Cancer Risk Factors
1. HPV infection 2. Smoking 3. Immunosuppression 4. Long-term oral contraceptive use 5. Overweight
31
Cervical Cancer Tx and Prevention
Prevention: Gardasil and Cervarix (vaccines) Tx: 1.Surgery 2. Cryo/laser/radiation/chemo therapy
32
Vagina fibromuscular canal | Composed of 3 layers
1. Mucuosa-**non-keratinized** stratified squamous epithelium 2. Muscularis: 2 layers of smooth muscle-inner circular and outer longitudinal 3. Adventitia: loose connective tissue that anchors vagina
33
Mammary Glands
* Modified sweat glands * 15-25 lobes * Grandular elements are arranged in a radial fashion around the nipple which ducts from secretory units empty into
34
What is Fibrocystic change of the breasts?
1. NOT a cancer 2. D/T hormonal stimulation of breast tissue 3. Results in dilated fluid-filled acini and stroma abundance 4. Small cysts-painful lumpy breasts 5. Symptoms follow menstrual cycle
35
What is the most common Breast Cancer?
Ductile carcinoma
36
Breast Cancer Screening Recommendations | (3)
1. Breast self-exam: monthly over age 20 2. Clinical breast exam: **q3 years** between 20-40 and **annually afterwards** 3. Mammography: annually age 40 or older | If family history of breast cancer-screening must start earlier
37
What is the typical duration of Female Reproductive Cylcle?
24-35 days **28 day average**
38
Menstrual Phase | What phase number and what days?
First phase Days 1-5
39
Preovulatory Phase | What phase number and what days?
Phase 2 Days 6-13
40
Ovulation | What phase number and what days?
Phase 3 Day 14
41
Postovulatory phase | What phase number and what days?
Phase 4 Days 15-28
42
What hormone is most active during each phase of the menstrual cycle?
**F**-FSH (menstrual phase) **E**-Estrogen (Preovulatory phase) **L**-LH-(Ovulation) **A**-ALL-(Postovulatory phase)
43
What meiotic phase do the oocyte arrest in?
Prophase I
44
What meoitic phase do secondary oocytes arrest in?
Metaphase II
45
What secretes estrogen and what are the main functions of estrogen? | 4 functions
Secretion by **ovarian follicles** 1. Promotes development and maintenance of female reproductive structures 2. Increases protein anabolism (including strong bones) 3. Lowers blood cholesterol 4. Inhibits GnRH (-ve feedback)
46
What secretes Progesterone and what does it do?
Secreted by **corpus luteum** 1. Works with estrogen to prepare and maintain endometrium for implantation and mammary glands for milk production 2. Inhibits GnRH and LH (-ve feedback)
47
What secretes Relaxin? What is the purpose of relaxin?
Secreted by **corpus luteum** 1. Relaxes uterus by inhibiting the contraction of myometrium 2. Increases flexibility of pubic symphysis and dilates uterine cervix (late pregnancy)
48
What secretes inhibin and what does it do?
Secreted by the **granulosa cells of growing follices** AND **corpus luteum** * Inhibits FSH and LH (-ve feedback)
