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

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
peritoneum or outside serous covering, the peritoneum of the broad ligament, covering the anterior and posterior surfaces and upper margin of Uterus
Perimetrium
the uterus is its upper larger part, above the smaller constricted cervix
Body
is that part of the body above the openings of the uterine tubes
Fundus
is the long narrow constricted lower 2.5 cm or 1 inch of the uterus, the neck
Cervix
(L) cervix = neck
is the narrow part at the junction of the body and the cervix
Isthmus
Formerly called internal os
is the space within the body. It is triangular in shape when viewed in front
Uterine cavity
is the narrow passage within the cervix that opens at its upper end into the body of the uterus, and at its lower end into the vagina
Cervical canal
is the opening between the cervical canal and vagina. It was formerly called external os
Uterine opening (NA ostium uteri)
two openings between the uterus and the medial ends of the uterine tubes
Openings of the uterine tubes
to provide an organ in which the fertilized ovum may develop
Uterus
sheath
vagina
is a membrane that partly closes the opening in the virgin
Hymen
passage from the cervix of the uterus to the outside of the body at the perineum. This canal is about 9 cm or 3.6 inches in length
Vagina
a condition in which there is no opening in the hymen
Imperforate hymen
The function of the vagina:
o To accommodate the penis during intercourse, and to receive spermatozoa as they are discharged from the male urethra
o To serve as a passage for menstrual discharge
o To form a birth canal through which the mature fetus is expelled during child birth
are branches of the internal iliac arteries reaching the laternal margins of the uterus by passing between the two layers of the broad ligament
Right and Left uterine arteries
drain the uterus, and empty into the internal iliac veins
Right and left uterine veins
is the area lying between the medial surfaces of the upper parts of thigh, and extending from the pubic arch anteriorly to the tip of the coccyx posteriorly
Perineum
two pairs of folds of the skin that run anteroposteriorly from the pubic arch almost to the anus
Labia
rounded prominence in front of the symphysis pubis, and is covered with hair
Mons pubis
a small rounded prominence in the midline below the symphysis at the anterior junction of the two labia minora
Clitoris
is the area between the medial margins of the labia minora behind the clitoris
