10.2 The Female Reproductive System Flashcards
Concerned with propagation of human race by:
- The production of the female reproductive cell which is the ovum
- The provision of passages by which the sperm and ovum may meet
- The provision of a cavity within which the fertilized ovum may develop and mature
- The production and secretion of female sex hormones
pertaining to reproductive organs
Genitals
the organ that produces ova (eggs)
Ovary
an alternate name for the ovary
Female Gonad
the female reproductive cell formed in the ovary
Ovum – female sex cell, egg, seed
pl. Ova
a reproductive cell, male or female
Gamete
the production of ova, by the ovary, and several miotic divisions necessary to produce a mature ovum
Oogenesis
the expulsion of an ovum from the ovary into the pelvic cavity. This occurs about once every 28 days, in the human female during the productive period of life
Ovulation
the union of a female ovum and a male spermatozoon, the beginning of an embryo
Fertilization
a fertilized ovum
Zygote
the discharge of blood and lining membrane of the uterus (womb), occurring about every 28 days, and lasting 4 days
Menstruation
the cessation of the periodic menstruation and production of mature ova by the female, occurring 45 to 50 years of age
Menopause
the beginning of ovulation and of menstruation in the female, with the development of secondary sexual characteristics
Puberty
The age of onset of puberty varies from ____
12 to 16
in female, the fold of peritoneum that covers the floor of the pelvis
Broad ligament
two flattened oval organs that lie one in each side of the pelvis, lateral to the uterus
Ovaries
Each ovary measures _____ in length
4 cm or 1.6 inches
egg bearer = forms egg
(G) oophoron
the ovary is the covering of modified peritoneum, derived from the broad ligament
Germinal epithelium
the mesentery of the ovary and consists of 2 layers of peritoneum that pass from the broad ligament to encircle the ovary
Mesovarium
a connective tissue stroma that contains many nest cells
Ovarian follicles
is a globular cell about 0.2 mm or 1/125 inch in diameter with a cell membrane, nucleus and at maturity containing 23 single chromosomes
Ovum
is a primary follicle that has undergone development. Manufactures estrogen
Vesicular ovarian follicle or Graafian follicle
a small sac with fluid
(L) vesicular
is the expulsion of a rope ovum
Ovulation
is a Graafian Follicle after the ovum has been expelled. It produces progesterone
Corpus Luteum
trumpet
(G) salpinx
also called fallopian tube or oviduct
Uterine Tubes
hollow tubes that pass, one from each upper angle of the uterus, to end close to the corresponding ovary. Each tube is about 10 cm (4 inches) long, and is open at both ends.
Uterine Tubes
The lateral end of the tube is enlarged and surrounding its opening there are fingerlike processes called
fimbriae – hence fimbriated end
abdominal opening (ostium) of the uterine tube is at its ____ of fimbriated end
lateral
the opening of the uterine tube into the uterus is at its ____ end, at the upper lateral border of the uterus
medial
convey the ovum that has been expelled from the ovary to the cavity of the uterus
Uterine Tubes
is flattened pear shaped hollow muscular organ measuring about 7.5 x 5 x 3.7 cm or 3x2x1 inches in size
Uterus
lining membrane of Uterus
Endometrium
muscular layer or visceral muscle of Uterus
Myometrium
