Chicken Wing Dissection Lab – Individual Analysis
How do muscles, bones, tendons and ligaments work together to move a joint in a chicken
wing and how do they compare to a human arm?
Vocabulary:
1. Muscle: __________________________________________________________________________________________
2. Tendon: _________________________________________________________________________________________
3. Ligament: _______________________________________________________________________________________
4. Fat: ______________________________________________________________________________________________
5. Cartilage: _______________________________________________________________________________________
6. Joint: ____________________________________________________________________________________________
Materials:
Dissecting pan
scissors
probe
hand lens
chicken wing
Procedure: Use the procedure on the colored paper. ONLY ONE PERSON IN YOUR GROUP
NEEDS TO COMPLETE the DATA TABLE for the group. I’m assuming every one will help tell
your recorder what to write!
Individual Analysis and Questions (To be completed individually, by EVERYONE!)
1. What joint in your body is similar to the one in middle of the chicken wing?
2. Do you think your chicken wing was from the left or right side of the body?
EXPLAIN how you know? Hint: the picture on procedure page is a right wing.
3. Name three bones in the chicken wing that are homologous (similar) to yours.
___________________________ __________________________ _________________________
4. Three types of structures are called connective tissues because they help
movement. Name the three connective tissues:
___________________________ __________________________ _________________________
5. Compare your observations of the tendons and ligaments.
a. Which was tougher and stronger? __________________________
b. Which was more flexible (bendy, stretchy) and easily torn? __________________
c. Suggest a reason for your answers above. Hint: consider each tissue’s job.
6. What would happen if cartilage were not present at the ends of the joints?
7. What tissue in the chicken wing is commonly referred to as “meat?” __________________
8. Using the correct vocabulary term, fill in the blanks to describe what happens as
you bend your elbow (or a chicken wing flexes).
The __________________ in the upper arm contracts, burning some of the energy stored
in the ____________. The __________________ attached to the muscle in the upper arm and
the bone in the lower arm pulls the lower arm up. The _______________ connecting the
lower arm bone and upper arm bone stretches while still holding the _______________
together. The __________________ between the bones helps cushion the motion so the
bones do not grind.
Match the word with the correct description.
______9. Connects bone to bone
A. Muscle
______10. Attaches muscle to bone
B. Cartilage
______11. Tissue that contracts for movement
C. Tendon
______12. Place where two bones meet
D. Ligament
______13. Cushions the motion of bones
E. Joint
______14. Cushions organs and provides energy
F. Fat
15. Examine the wing bones diagram below comparing the wings of five different birds.
a. How are they alike?
b. Why do you think the albatross’ wing is
so much longer than the
hummingbird’s?
c. Chickens are not good flyers. Propose a
reason for this based on its bone structure.
