1 Skeletal & Muscular Systems Chicken Wing Dissection

2 Name: What is Really in a Chicken Wing? Use the picture to the left to answer the following two questions: Doctors often have to do surgery to repair torn ligaments or injured joints for professional athletes. What does it take to be a good doctor? Why are the doctors dressed like that? You are going to be a surgeon today! On a chicken wing! Materials: protective gloves chicken wing safety goggles scissors plate or dissecting tray Problem: What would you expect to find inside of a chicken wing? Get into a group of 4. Assign a role to each group member and write that person s name on the line. Chief Scientist (keeps students on track with lab procedures and records information) Materials Manager (in charge of getting, cleaning, providing, and putting away materials) - Timekeeper/assistant

3 Chicken Wing Handler Procedures: Look at the wing where it was removed from the body. (Depending on the way the wing is cut, you might see cartilage and bone marrow). what you see in the box below. Label and the cartilage and bone marrow if you can see them. Label the skin. Describe what you think the function of the skin and bone marrow might be. ing Function of Skin (and bone marrow if you can): Watch the video. Describe how they remove the skin: When the teacher has approved your procedure, go ahead and do it. what you see in the box below. Label as many parts as you can.

4 As you go through each section, see if you can find the parts! When you find them, draw what you find and answer the question(s). Fat: Look for yellowish tissue clumped together beneath the skin. This is fat tissue, made of fat cells. what you see in the box below. Label the fat. Describe what you think the function of the fat might be. Function Muscles: The muscles in the wing look like bundles of pale pink tissue. Find two muscles in the wing that bend and straighten the elbow joint. Each muscle pulls on the lower wing bones in one direction. Hold the wing down at the shoulder and alternately pull on each muscle. Observe what happens. OR describe what happens when you pull on each muscle. Then describe HOW that happens in the next box. /Describe Describe HOW

5 Tendons: Tendons are shiny white tissues at the ends of the muscles that attach muscles to bones. Find as many tendons as you can on the chicken wing. Pull on a tendon to see how it helps the chicken move its wing. what you see in the box below. Label the tendon and describe what you think the function of the tendon is. Function Joints and Ligaments: Two bones come together at a joint. Ligaments connect bones to other bones at joints. Bend and straighten the elbow joint and observe how the bones fit together. Ligaments look like a shiny white covering of the joint surfaces. Closely examine the elbow joint between the upper wing and the lower wing and identify the ligaments. Describe how the joint and ligament help the wing move Cartilage: Between the bones is another shiny, slippery white material. This is cartilage, which helps the bones move without grinding against one another. 1. Locate the cartilage 2. it, and describe how it helps the joint work. Describe Clean up Time: When you have finished observing the wing and writing your notes: Throw the chicken remains away. Wash all equipment in hot, soapy water. Wipe down your table.

6 Wash your hands with hot water and soap. Answer the summary questions. 1. Which joint in the human body is similar to the joint you studied? Why do you think so? 2. Explain how muscles work in pairs to move a chicken wing. 3. How does skin protect against infection? 4. What is the difference between voluntary and involuntary muscles? Give an example of each in the human body. 5. Which kind of muscles (voluntary or involuntary) were you looking at in the chicken wing?

7 Contents: - Cover Page - Lab Instruction Sheet - Teacher Usage Notes with links to video clips Usage Notes: Students love this lab!! They tend to get very easily grossed out, and very excited so be prepared for some screaming, or needing to go wash their hands. You may want to have them wear goggles as an extra precaution. Materials you will need include: Chicken wings (make sure to get the wing sections, not the split wings), dissecting scissors, paper plates, gloves, goggles, soap and water). I like to show the following video clip: Other good choices are: (longer about 11 min) There are many others available by searching for chicken wing dissection Please use this product for educational purposes only.
