Chicken Wing Dissection Activity

The document is a lab report for a chicken wing dissection. It provides instructions for students to follow to dissect a chicken wing in order to observe how the muscular and skeletal systems work together. It also includes analysis questions for students to answer about the structures and functions they observed during the dissection, such as identifying bones and joints, describing ligament function, and relating chicken wing structures to comparable human anatomy.

Chicken Wing Dissection

Purpose:
● Observe how the muscular and skeletal systems
work together to move/support a chicken’s wing

● Relate this to the arrangement of comparable


anatomical structures of the human body.
Procedure:

1. Put on gloves and obtain the following materials:


a. Chicken wing
b. Dissecting tray & equipment

2. Pat the chicken wing dry with a paper towel.

3. Carefully remove the skin using a scalpel without cutting through the underlying
muscles/structures.
a. This is difficult so take your time. This works best when you make an incision and slide your
finger under the skin to break up the fascia.

4. Locate the two muscle bundles that bend and straighten the lower section of the wing (below the
elbow joint) by pulling on each muscle in turn
a. Note how these muscles are in opposition with each other.

5. Hold the wing at Joint A in Fig. 1 and alternatively pull each muscle to observe flexion and
extension.

6. Follow a bundle of muscle down to the tendon. Pull on a tendon to see how it helps move the wing.

7. Notice the ligaments at the joint. Observe their arrangement with the bones at each of the joints
A, B, C.

8. Remove the muscles and tendons from the bone to expose Joint B. Pull these bones apart at the
joint.
a. Observe the ends of the bones. Identify the articular cartilage.

9. Carefully break one of the bones and look inside. You may ask the instructor to use a bone cutter.
a. Identify the marrow.

10. CLEAN UP: Collect the chicken remains and put them into the red biohazard bag (keep your gloves
on)
a. Wash off the dissection trays and tools with soap and water. Place the tools in the drying
rack.
b. Wash your hands well with soap and water
