01. GYN Overview Flashcards
Lateral fornices
Pouches lateral to the cervix that contain the broad ligaments; the ovaries and fallopian tubes may be palpated here
Layers of the Uterus
Endometrium (innermost); Mymetrium (muscular); Perimetrium (peritoneal covering)
Isthmus
Nonmobile, medial portion of fallopian tube that has a narrow lumen
Ampulla
Most common site for ectopic pregnancies
Fimbrae
Direct egg into fallopian tube
Lymphatic drainage of vulva and lower vagina
Inguinofemoral lymph nodes, then external iiac chains
Lymphatic drainage of cervix
Parametria (cardinal ligaments) to pelvic nodes (hypogastric, obturator, external iliac groups)
Lymphatic drainage of endometrium
Thru broad ligament and infundibulopelvic ligament to the pelvic and para-aortic chains
Lymphatic drainage of ovaries
Via the infundibulopelvic ligaments to the pelvic and para-aortic chains
Adrenarche
Change in adrenal gland a/w production of androgen (~ age 8)
Tanner Stage I (females)
0-15 yrs; Pre-adolescent breasts; No pubic hair
Tanner Stage II (females)
8-15 yrs; Breast budding (thelarche); areolar hyperplasia w/ small breast tissue; Long downy pubic hair near labia; Peak growth velocity often occurs soon after stage II
Tanner Stage III (females)
10-15 yrs; Further breast tissue enlargement; no separation of areola contours; Increase in amount and pigmentation of pubic hair; Menarche in late stage III (2% of girls)
Tanner Stage IV (females)
10-17 yrs; Separation of contours; areola and nipple form secondary mound above breast tissue; Pubic hair adult in type but not distribution; Menarche occures in most girls in stage IV, 1-3 yrs after thelarche
Tanner Stage V (females)
12.5-18; Large breast with single contour; Pubic hair has adult distribution; Menarche occurs in 10% of girls in stage V.
Metrorrhagia
Uterine bleeding at irregular intervals
Polymenorrhea
Menstrual cycles with intervals of 21 days or fewer
Mittelschmerz
One-sided, lower abdominal pain associated with ovulation
Leiomyoma
Benign tumor derived from muscle, most often of the uterus (AKA fibroid)
Hypothalamic reproductive cyle hormone
GnRH (gonadotropin releasing hormone)
Pituitary reproductive cyle hormones
FSH; LH
Ovarian sex steroid reproductive cyle hormones
Estrogens (17B-estradiol; estrone; estriol); progesterone
Function of FSH
Stimulates graafian follicles of ovary; assist follicular maturation and secretion of estradiol
Function of LH
Stimulates final RIPENING OF FOLLICLES and the SECRETION OF PROGESTERONE their rupture to RELEASE THE EGG; and CONVERSION of RUPTURED FOLLICLE into CORPUS LUTEUM
