Ch8 Female Repro System Flashcards
fertilization
when 2 gametes unite to form a single nucleus with 1/2 chromosomes and genetic code from each parent
ovulation
egg leaves the ovary, travels down the fallopian tubes to uterus for implantation
female and male sex cells are called…
gametes (ovum, sperm)
female and male gonads
ovary, testes
stages of embryo
zygote - fertilized egg
embryo - 2-8 weeks
fetus - 8 weeks to term
menarche
female’s first period
menopause
when all eggs have been released, hormone production slows, and menstruation ends
placenta
vascular organ implanted in uterus to nourish the embryo
pituitary gland
gland that secretes hormones that govern the reproductive functions of the ovaries, breasts, and uterus
female secondary sex characteristics
body hair
breast development
structural changes in bones and fats
gynecology
study of female reproductive system
obstetrics
specialty concerned with pregnancy and delivery of a fetus
neonatology
study of care and treatment of a newborn
cul-de-sac
region midway between the uterus and rectum
Bartholin glands
2 small glands at vaginal opening that produces mucus secretion that lubricates the vagina
vulva
outer area containing clitoris, perineum, labia, and hymen
utero-ovarian ligament
holds ovary in place on the side of the uterus
corpus luteum
ruptured follicle after ovum is released
adnexa
collectively refers to fallopian tubes, ovaries, and supporting ligaments
fimbrae
finger-like ends of the fallopian tubes
layers of the uterus
endometrium - inner layer of specialized epithelial mucosa
myometrium - middle muscular layer
perimetrium - outer layer (uterine serosa)
parts of the breast
- glandular tissue containing milk glands
- lactiferous ducts
- sinuses carrying milk to the nipple
- mammary papilla (nipple)
- areola
parturition
giving birth
lactation
secretion of milk
phases of the menstrual cycle
Days 1-5 - period
Days 6-12 - endometrium redevelops, estrogen released
Days 13+14 - ovulation
Days 15-28 - empty egg follicle becomes corpus luteum, which functions as an endocrine organ (making estrogen and secreting progesterone)
prementrual syndrome (PMS)
combination of symptoms of depression, breast tenderness, and irritability caused by lower levels of progesterone and estrogen
chorion
outer membrane surrounding the developing embryo
amnion
inner membrane filled with fluid that holds the fetus suspended in amniotic cavity
cephalic presentation
normal delivery position - head first
3 phases of labor
cervix dilation
birth of infant
placenta delivery
follicle-stimulating hormone
- produced by pituitary gland
- target organ: ovary
- stimulates maturation of the ovum
luteinizing hormone
- produced by pituitary gland
- target organ: ovary
- stimulates ovulation
estrogen
- produced by ovary and placenta
- target organ: uterus
- builds endometrial lining
progesterone
- produced by ovary and placenta
- target organ: uterus
- sustains uterine lining and placenta
human chorionic gonadotropin (hCG)
- produced by placenta
- target organ: corpus luteum
- sustains pregnancy
LH surge
spike in LH levels that triggers ovulation
common symptoms of menopause
hot flashes, insomnia, vaginal atrophy
amni/o
amnion
bartholin/o
Bartholin glands
cervic/o
cervix
chori/o
chorion/o
chorion
colp/o
vagina
