Integrated Science Name _________________________________________ 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.
