The Female Reproductive System Flashcards
(44 cards)
Anatomy of the Female Genital Tract
Consists of ovaries, uterus, fallopian tube, vagina, and vulva
* Ovaries divided into cortex and medulla
* Uterus divided into cervix, corpus, and fundus
* Cervix divided into vaginal portion and endocervix
First half of Menstrual Cycle
Endometrial glands and stroma proliferate under influence of estrogen from ovarian follicle
Midcycle
Ovulation occurs;
* Follicle discharges an egg, becomes a corpus luteum that produces estrogen and progesterone
* Progesterone: Endometrium undergoes secretory phase to prepare for receiving fertilized ovum
If no pregnancy occurs (in Normal Mestrual Cycle)
- Corpus luteum degrades
- Estrogen and progesterone levels fall
- Secretory endometrium is shed with blood
- New cycle begins
Female Genital Tract Infections
Vaginitis; Cervicitis; Salpingitis; PID; Condylomas;
Vaginitis
Common; causes vaginal discharge, itching, and irritation
* Candida albicans
* Trichomonas vaginalis
* Gardnerella (Haemophilus) vaginalis in conjunction with anaerobic bacteria
(nonspecific vaginitis)
Cervicitis
Mild chronic inflammation; common in women who have had children
* More severe inflammation caused by gonococci or Chlamydia
* May spread to infect tubes and adjacent tissues; pelvic inflammatory disease
(PID)
Salpingitis
Tubal infection
PID - pelvic inflammatory disease
Inflammation of fallopian tubes, along with ovaries at times
Condylomas
Venereal warts in genital tract
* Benign tumorlike overgrowths of squamous epithelium
* Acquired and transmitted by sexual contact
Toxic Shock Syndrome (TSS)
Caused by toxin produced by staphylococci
* First associated with tampon use; occurred in vagina
* Also occurs from staphylococcal infections of skin, bones, kidneys, with toxin released in the bloodstream
Clinical Manifestations of TSS
- Fever, vomiting, diarrhea, muscle aches and pains
- Erythematous or sunburn-like rash followed by flaking and peeling
Treatment of TSS
- General supportive measures until effects of toxin wear off
- Antibiotics to eradicate staphylococci do not shorten course of disease
Condylomas of the Genital Tract
- Venereal warts
- Caused by human papillomavirus (HPV)
- Occur most often on the vulvar mucosa and around the vaginal
opening and the anus
Diseases of the Vulva
Vulvar dystrophy; Carcinoma of the vulva
Vulvar dystrophy
- Irregular white patches on vulvar skin (leukoplakia)
- Intense itching
- May progress to carcinoma
- Local treatment usually effective
Carcinoma of the vulva
- Found in pre- and postmenopausal women
- Usually with a preexisting vulvar dystrophy
- Treated by vulvectomy and excision of inguinal lymph nodes
Cervical polyps
- Benign, arise from the cervix
- Usually small but may be quite large
- Erosion of tip may cause bleeding
- Surgical removal
Cervical dysplasia
- Abnormal growth and maturation of cervical squamous epithelium
Mild dysplasia
Result of cervical inflammation
* Regresses spontaneously
Severe dysplasia
Does not regress
* May progress to in situ carcinoma
* May progress to invasive carcinoma
Cervical Intraepithelial Neoplasia
Constitute different stages in a progressive spectrum of epithelial abnormalities classified as cervical intraepithelial neoplasia (CIN)
* Grade I: Mild dysplasia
* Grade II: Moderate dysplasia
* Grade III: Severe dysplasia
Some HPV strains that cause cervical condylomas are carcinogenic and predispose to cervical neoplasia
Diagnosis of Cervical Intraepithelial Neoplasia
HPV test to supplement Pap smear when cytologic changes in Pap smear are inconclusive (atypical squamous cells of undetermined significance)
* If HPV test is negative, cytologic changes are not significant
Irregular Uterine Bleeding
Occurs because follicle fails to mature and no corpus luteum is formed (anovulatory cycle)
* Disturbance of normal cyclic interaction of estrogen and progesterone on the endometrium
* Uterus is subjected to continuous estrogen stimulation and responds by shedding and bleeding in an irregular manner instead of shedding all at once as in a normal menstrual cycle (anovulatory bleeding)
