Joint part 2:
Joint B
Joint C
Joint A
a. Do you think your wing is from the right or left side of the chicken? Explain
b. Imagine that the wing is a human arm. Create and observe movement in the joints. Use your wing and
Figure 1 to answer questions B through E below:
1.
Which joint in the human body is the equivalent to joint A? Why do you think so?
2. What TYPE of joint do you think Joint A is? (wing to body)Explain your answer.
3. Which joint in the human body is the equivalent to Joint B?(Moves wing at elbow) Why do you
think so?
4. Which joint in the human body is the equivalent to Joint C? Why do you think so?
Remove the muscles and tendons from the bone to expose Joint B. Pull the bones apart at the joint. Look for
the ligaments that hold the bones together. If you can, locate two ligaments crossing each other. These are the
cruciate ligaments (often injured by athletes).
5. How did ligaments hold the bones together? What would happen if you cut the ligament?
6. Pull apart a joint and observe the ends of the bones. What type of material do you see on the ends of the
bones making up the joints? What purpose does this serve?
CLEAN UP: Collect the chicken remains and place them in the trash. As a hygienic precaution, keep the gloves on your hands.
Wash dissection tray and tools. Afterward, remove your glove and discard in the trash. Make sure you wash your lab station. WASH
YOUR HANDS VERY WELL WITH SOAP AND WATER!!
Note: if you do not finish the procedural portion of the lab in one period you must save your specimen. Write your names on a bag
then put your chicken wing in a labeled bag. You may have the next period to finish up your observations.
