INLAB EXERCISES
Use the following modules in Visible Body’s Human Anatomy Atlas app to guide your exploration
of the reproductive system.You can manipulate the images to see different views and isolate each
structure. Be sure to select the book icon under the structure name to read information specific to
that structure.
As you explore the modules, locate the organs and related structures on any additional charts,
models, or specimen available.
Make the following observations, and note that you are responsible for all bold terms and diagram labels

1. Scroll down to 13. Reproductive System (F). In this view, with the skin faded, you can see the paired
mammary glands (breasts) and the internal organs inside the pelvis. Choose the skeletal system
icon on the left (skull) to hide the bones. This gives you a view of the internal reproductive organs
within the pelvis. Select the skull icon again to see how these organs are protected by the bones of the
pelvis.
I. FEMALE REPRODUCTIVE SYSTEM OVERVIEW
To Start: Select the Views menu at the top of the screen, then select Systems. Scroll down to the
Reproductive system at the bottom and choose on Show More to display all of the reproductive
system views.
Mammary
glands (breasts)
Internal
reproductive organs
4
Left puborectalis
muscle
Left iliococcygeus
muscle
Left pubococcygeus
muscle
Left coccygeus
muscle
2. Return to the Systems view, and in the reproductive system section, select Show More. Navigate to
16. Pelvic Floor. Observe the muscles that make up the floor of the pelvis (levator ani, coccygeus,
associated connective tissue). These will support the weight of the developing fetus during pregnancy.

Fundus of uterus
Right Fallopian tube
Endometrium of uterus
Vagina
Cervix of uterus
Body of uterus
Right ovary
3. Navigate to 17. Uterus. Observe the following parts of the uterus in this cross section: fundus,
body, cervix, and endometrium. The endometrium is where the embryo implants and develops
during pregnancy.
a. What is produced by the cervix?
6
Ureters
Right ovary
Rectum
Vagina
Right Fallopian
(uterine) tube
Uterus
Bladder
4. Navigate to 18. Location of Organs. Locate the rectum, the bladder, and the ureters; note their
position with respect to the uterus. Choose the urinary system from the systems list on the left (the
kidney icon) and deselect it. Now you can see the primary organs of the female reproductive system.
Locate the following: ovaries, uterus, uterine tubes, and vagina.

5. Select 20. Ovary section.
a. Locate the following structures and state the role of each one in reproduction.
i. Uterus
ii. Uterine tubes
iii. Fimbriae
iv. Ovarian ligaments
b. Observe the section of the ovary. On the right is a series of developing follicles containing
developing oocytes. The largest one is about to burst and will release its oocyte, to be taken
up by the fimbriae of the uterine tubes. The remaining empty follicle collapses and releases
hormones that support pregnancy for a short time. Read the definition of the ovary and answer
the following questions.
Uterus
Right ovary
Developing follicles
containing oocytes
Right fimbriae
Right Fallopian
(uterine) tube

i. What are the female sex cells (gametes) called?
ii. What percentage of the genetic information passed to the fertilized egg comes from the
egg (oocyte)?
iii. Which two important hormones are produced by the ovaries?
iv. What are the roles of these hormones?
v. Define ovulation.
vi. Where do oocytes go after they are ovulated?
9
Left ovary
Vagina
Uterus
Bladder
Urethra
6. Select 21. Vagina and Urethra. Locate the vagina and select it, then read the definition.
a. The vagina extends from the uterus to the _________________________.
b. List the three main functions of the vagina.
c. The wall of the vagina contains _________________________ and is lined with
_________________________.
d. Deselect the skeletal system by choosing the skull icon in the list on the left. Rotate the model
slightly in order to locate the urethra and note how it also ends at the vestibule (vulva).

Clitoral glans
External opening of
the vagina
External urethral
orifice
Labia majora
Vestibule
Perineum
Labia minora
7. Select 22. External Genitalia (F).
a. Locate and name the female genitalia.
b. Choose the vestibule then locate the external urethral orifice and the external opening of
the vagina.
c. Locate the prepuce. What male structure is analogous to the female prepuce?
d. Select each of the labia majora and note that they do not fully surround the labia minora. What
is the name of the region of skin that borders the labia minora posteriorly?

Left mammary
gland lobules
Left lactiferous ducts
8. Select 23. Breasts.
a. Select either of the breasts (mammary glands) and read the definition. Mammary glands are
modified ________________________________ glands.
b. Choose the skin icon (head) in the list to the left, and locate the nipple and the areola in the
center of each breast.
c. Refresh the model and then select either breast. Hide the breast to reveal the lobules and
ducts inside. Select any of the lobules and read the definition. What do these lobules produce in
lactating females?
d. These lobules open into ________________________________ that carry milk to the
________________________________. Select any of the lactiferous ducts and zoom in to see how they
converge in the nipple. Breastfeeding causes milk to be ejected from the nipple.

II. PELVIS CROSS SECTION
In the Cross Section tab, scroll down to the Pelvis (Axial) section and select 4. Pelvis S05 (F). Use
the Flip button in order to view the section from the other side.
You can see the fundus of the uterus through the peritoneum. Locate the uterine tubes and the ovaries.
Locate the fimbriae surrounding each ovary. Now flip the section over again to view the section from
beneath. Locate the myometrium (muscular inner layer) and the endometrium.
You can also see the underside of the ovaries in this view.
