Menustration Flashcards
Luteinizing Hormone
The LH surge results in establishment of the corpus luteum, which produces estrogen and progesterone. LH rises and stimulates the follicle to produce estrogen. As estrogen is produced by the follicle, estrogen levels rise, inhibiting the ouput of LH.
The menstrual cycle hormones
GnRH, FSH, LH, Estrogen, Progesterone, Prostaglandins
When does ovulation occur
After LH surge damages the estrogen-producing cells, resulting in a decline in estrogen
Labia majora
Crescent shaped fatty tissue containing folds of skin; extends down from mons veneris to perineum
Labia minora
Narrow folds of hairless skin between labia majora and vagina
Clitoris
Short, sensitive, erectis tissue, anterior junction of the vulva
Perineum
Area between vaginal opening and anus composed of muscles and fascia, which supports pelvic structures
Hymen
Membranous tissue over vaginal opening
Urethral opening
Beneath clitoris
Ovaries
Small oval organs located on each side of the uterus in the upper part of the pelvis; function in the development and expulsion of ova
Fallopian tubes (oviduct)
Two tube, each closely adjoining an ovary. Each has two openings- one into the abdominal cavity and one into the uterine cavity. Function to conduct the released ovum from the ovary to the uterus
Uterus
Hollow, pear shaped thick walled muscular structure, located between the bladder and the rectum in the pelvic cavity. Composed of 3 sections: fundus, body, and cervix. Consist of the myometrium, endometrium. During labor expels the product of conception
Myometrium
Involuntary muscle fibers that provide for expansion and support during pregnancy and for expulsion of fetus and control of hemorrhage during labor and delivery
Endometrium
Highly vascular lining that provides for implantation of fertilized ovum, she’d during menstruation
Vagina
Distensible mucous membrane- lined passage ( birth canal) located between the bladder and rectum
