1. Fetal Pig Dissection
The fetal pig is a mammal like us so it has many structures that are similar to ours.
The anatomy class will analyze the structure and function of the external and internal parts of the fetal pig relating it to human structures.

2. Lab 1-External structures:
In this lab, you will:
Locate external structures and state the functions of those structures.
Locate the bones listed on the lab sheet by region.
Answer general questions about the pig.

4. Procedure: You will be assigned a partner, a pan,
and a dissection kit (It is your
responsibility to clean and dry
your kit and pan each day. Also,
clean your table. It will be checked
and points removed if it is not.)
At the appointed time, you will pick up a pig from the bucket. You will place a safety pin with colored beads on the ear so that you can remember which pig is yours when it is returned to the bucket. Get the same pig each day.
Make sure you stay at your assigned table until told to put your pig up. No horse play. This is a time for learning not just socializing.

5. External Features Lab:
Using the lab manual you were given, answer the questions that are on your lab hand-out
At the appointed time, locate the external structures and bones of the pig
Tomorrow, you will be tested on the location of the structures as well as any information you were asked on the lab sheet.

6. External pig parts:

7. Both sexes have:
Nipples and umbilical cord

8. Distinguishing between sexes:
Female-urogenital
pappila by anus
Male: urogenital opening is by umbilical cord
Also, may see scrotum sacs

9. Looking at the mouth:
Cut jaws like illustrated

10. Epiglottis, glottis and soft palate:
Locate epiglottis (1) and soft palate (2)
Glottis is
#2 and epiglottis is #1

11. Palates and nasal opening:
Hard palate (1) Soft palate (2) Internal nares (3)

12. Nictating Membrane:
In corner of eye/3rd eyelid

13. Bones of fetal pig: 1. Locate major bones listed on lab sheet
2. State function(s)
of each bone.

14. Muscle groups: Remove the skin (very carefully) from your pig
Locate the muscles circled in lab booklet.

15. Internal pig structures:
Cut the pig as
illustrated
Do not go deep
Around the
Umbilical cord
Open it up and pin
it down to the
pan

16. Internal structures: Your pig dissection should look like the pictures
(remember to cut gently around the umbilical cord-do not cut the vessels connected to it)
Locate structures
and write the
function of the
structures on
your hand-out (picture on the next slide)

17. Picture of internal structures:

18. Urinary system:
Locate kidneys, ureter, bladder, colon

19. Male reproductive system:
Locate:
epididymis
penis
testes
scrotum

20. Female reproductive system:
Locate:
fallopian tubes (2)
ovaries (1)
bladder (6)
horn of uterus (3)

21. Fetal pig brain: Cut as illustrated in this picture
(remove top of Skull very carefully)

22. Measuring the intestines:
Remove intestines as a large mass (ball)
Separate the intestines by getting the messentery that holds them together
The pair with the longest intestines gets 25 bonus points on a test and the bragging rights for the longest intestines (it’s a pride thing!)
Must be finished by 8:25 (no later)
