chapter 8 Flashcards
female reproductive system
sexual reproduction:
-union of the nuclei of the ovum and sperm cell
-ovum and sperm are gametes
-each gamete contains half the # of chromosomes of a normal body cell
gametes (ovum and sperm):
-produced in gonads
-female gonads are ovaries and male are testis
fertilization:
-ovum leaves the ovaries and travels through the fallopian tubes
-fertilization takes place if sperm cells are present and unite with the ovum
-fertilized egg implants then divides to form a zygote(and later an embryo then fetus)
organs of the female reproductive system:
-ovaries, fallopian tubes & uterus
-cul-de-sac, vagina & Bartholin glands
-utero-ovarian ligaments, ovarian follicles & ovum
-corpus lute, endometrium & myometrium
-uterine serosa, clitoris & perineum
anatomic structure of the breast (sagittal view)
-glandular tissue
-fatty tissue
-ducts
-sinuses
menstruation (menstrual cycle)
-day 1-5: blood cells, endometrial cells, and glandular secretions discharge from the body
-day 6-12: estrogen aids repair of the endometrium, ovum grows on follicle
-day 13-14: the egg leaves the ovary and passes through the fallopian tube
-day 15-28: corus lute secretes progesterone, and the uterus lining builds up
pregnancy:
-if fertilization occurs, the egg implants in the uterine endometrium
-the placenta forms, and attaches to the uterine wall
-amnion holds the fetus in an amniotic cavity
-nutrients, oxygen, and wastes exchange between the fetus and mother
-placenta produces human chorionic gonadotropin (hCG)
-placenta, chorion & amnion membranes
three stages of labor:
- dilation and thinning of the cervix
- birth of infant
- delivery of placenta
hormonal interactions:
-pituitary gland secretes: follicle-stimulating (FSH) & luteinizing hormone (LH)
-pituitary gland stops producing FSH & LH during pregnancy & during oral contraceptives
menopause:
-gradual ending of the menstrual cycle
-begins between ages of 45-55
-falling estrogen levels
adnexa uteri
fallopian tubes, ovaries, and supporting ligaments
amnion
innermost membranous sac surrounding the developing fetus
areola
dark-pigmented area surrounding the breast
bartholin glands
small, mucus-secreting exocrine glands at the vaginal orifice
cervix
lower, neck-like portion of uterus
clitoris
sensitive erectile tissue anterior to the opening of the urethra
coitus (copulation)
sexual intercourse
corpus luteum
empty ovarian follicle, secretes progesterone after release of egg cell
cul-de-sac
region in lower abdomen, midway between the rectum and uterus
embyro
stage in prenatal development from 2 to 8 weeks
endometrium
inner, mucous membrane lining of the uterus
estrogen
hormone produced by the ovaries that promotes female secondary sex characteristics
fallopian tube(oviduct)
one of a pair of ducts through which ovum travels to the uterus
fertilization
union of sperm cell and ovum from which the embryo develops
fetus
stage in prenatal development from 8 to 39 or 40 weeks
fimbriae (singular: fimbria)
finger/fringe-like projections at the end of the fallopian tubes
follicle-stimulating hormone (FSH)
secreted by pituitary gland to stimulate maturation of the ovum
gamete
male or female sexual reproductive cell (sperm or ovum)
gentitalia (genitals)
reproductive organs
gestation
period from fertilization of the ovum to birth
gonad
female or male reproductive organ that produces sex cells and hormones (ovary & testis)
gynecology
study of femal reproductive organs, including breast
human chorionic (hCG)
hormone produced by placenta to sustain pregnancy by stimulating ovaries to produce estrogen and progesterone
hymen
mucous membrane partially or completely covering the opening to the vagina
labia
lips of the vagina
lactiferous ducts
tubes that carry milk within the breast
luteinizing hormone (LH)
secreted by the pituitary gland to promote ovulation
mammary papilla
nipple of breast
menarche
beginning of the first menstrual period and and ability to reproduce
menstruation
monthly shedding of uterine wall
myometrium
muscle layer of the uterus
neonatology
branch of medicine that studies the disorders & care for the newborn (neonatal)

orifice
an opening
ovarian follicle
developing sac enclosing each ovum within the ovary
ovary
one of a pair of female organs on each side of pelvis, almond-shaped, produce egg cells & hormones
ovulation

ovum (plural: ova)
mature egg cell (female gamete)
parturition
act of giving birth
perineum
