OB Mod III Test Review Flashcards
Homologous
Fundamentally similar in structure and function
Influence the development of secondary sex characteristics
androgens and estrogens
stimulate the processes of spermatogenesis and maturation of ova
FSH and LH of the anterior pituitary
The ovary is sensitive to
FSH, LH
The uterus is sensitive to
estrogen and progesterone
Estrogens inhibit….productions and stimulate….production
FSH, LH
Hormone of pregnancy
Progesterone: allows pregnancy to be maintained
Relaxes smooth muscles and is a potent vasodilator
PGE Prostaglandin E
Can be placed in cervical canal for cervical ripening: prepidil, cervidil, hospital prepared
Potent vasoconstrictor and increases contractility of muscles and arteries
PGF Prostaglandin F
Two phases of the ovarian cycle
follicular phase 1-14; luteal phase 15-28
Hormones that cause the testes to produce testosterone
FSH, LH
Stimulates the glandular tissue of the uterus
Estrogen
Secrete a thick, sticky mucus that accumulates and forms the mucous plug
endocervical glands
Goodell’s sign
softening of the cervix
Chadwick’s sign
bluish discoloration of the cervix
Causes a thickening of the vaginal mucosa, a loosening of the connective tissue, and an increase in vaginal secretions
estrogen
Common in the first trimester and may result from several factors, including elevated human chorionic gonadotropin hCG levels, relaxation of the smooth muscle of the stomach, and changed carbohydrate metabolism
nausea and vomiting
Causes smooth muscle relaxation
progesterone
Promotes uterine contractility and stimulates ejection of milk from the breasts
Oxytocin
TPAL
t: term; number of term infants born
p: preterm; number of preterm infants born
a: abortions; number of pregnancies ending in spontaneous or therapeutic abortion
