Module 8: Female Reproductive System Flashcards
(371 cards)
What is sexual reproduction?
The union of the nuclei of the ovum (female sex cell) and the sperm (male sex cell) that results in the creation of an embryo
gamete
sex cell
how many chromosomes are in a sex cell?
exactly half the number of chromosomes of a normal body cell
gonads
special organs in males and females that produce the egg and sperm cells
what are female gonads called?
ovaries
what are male gonads called?
testes
What is the route of an ovum after it leaves the overaies?
It travels down on of two fallopian tubes leading to the uterus (womb)
coitus
copulation, sexual intercourse
What is fertilization?
After coitus (sexual intercourse) the sperm cell travels into the fallopian tube where they can penetrate the ovum
zygote
The fertilized ovum
What is an embryo?
After many cell divisions of the zygote, a ball of cells form which typically takes 2-8 weeks
what is a fetus?
The embryo continues to grow in the uterus after 8-38 or 40 weeks it reaches full-term
gestation or pregnancy
the period of development within the uterus
ova
eggs
menarche
the occurrence of the first cycle
menopause
when all eggs have been released, hormone production diminishes, and menstruation ends
menstruation
When the eggs begin to mature and are released from the ovary in a 21-28 day cycle when secondary characteristics develop
placenta
A new, blood-vessel-rich organ connected to the embryo by the umbilical cord develops to nourish the embryo which implants in the uterine lining
What happens if fertilization does not occur?
Hormone changes result in the shedding of the uterine lining and bleeding and menstruation occurs
What are the hormones of the ovaries?
estrogen and progesterone
pituitary gland
located at the base of the brain, secretes other hormones that govern the reproductive functions of the ovaries, breasts, and uterus
gynecology
the study of the female reproductive system (organs, hormones, and diseases)
obstetrics
a specialty concerned with pregnancy and the delivery of the fetus (Latin: obstetrix means midwife)
neonataology
the study of the care and treatment of the newborn
