Read pages 815-818 in Silverthorn, focusing on figure 26.9a and 26.9b.
For our study of female reproductive anatomy, we will look at two videos from Acland's Video Atlas of Anatomy that show the internal reproductive structures. Note that the view of the uterus inside the body is quite different than what is shown in figure 26.9a. The uterus usually tips forward over the bladder, and is contained within a sheet of peritoneum called the broad ligament. The uterus has three parts: the fundus, the body, and the cervix. The fundus is the part of the uterus that curves up between the uterine tubes. The body is the main part of the uterus. The cervix (cervix means "neck") is the part of the uterus that protrudes into the upper part of the vagina. The structure of the cervix is critical to maintaining a pregnancy to full term.
The female gonad is the ovary.
Each ovary is attached to the side of the uterus by an ovarian
ligament, and can really only be seen from the posterior
side of the broad ligament. In ovulation, an egg is released
to the peritoneal cavity, and needs to be transported to the
uterus via the uterine tube
(also called the Fallopian tube
or oviduct). The
distal ends of the uterine tubes have many fingerlike projections
called fimbriae that envelop
the ovary and make sure that the egg gets swept into the uterine
tube, where fertilization occurs. The fertilized embryo then
moves slowly (it takes about a week) to the uterus, where it
implants into the wall of the uterus to begin development.
The videos contain more detail and terminology than I expect you
to learn for this class. You are required only to identify the
terms listed below in purple boldface. The links to the videos
will open in a new tab.
Video 5.3.8 (run
time: 4:33) This video shows an isolated
reproductive tract, which will allow you to see the three
regions of the uterus. It also shows the uterus and
associated structures in the pelvic cavity.
Video 5.3.9 (run
time: 3:46) This video shows the various ligaments
associated with the uterus. It is valuable because towards
the end it shows a uterus in a living body, filmed during
laparscopic surgery.
What to identify in the videos:
fundus of uterus
body of uterus
cervix of uterus
vagina
uterine tube/Fallopian tube/oviduct
fimbriae
ovary
broad ligament
