Step-by-Step Dissection Procedure and Answers

This section details the typical steps involved in dissecting a chicken wing, along with common questions and their answers to guide students through the process.

1. External Examination

• Identify the wing's outer features: feathers, skin, and muscle coverage.
• Question: What external features help identify the anterior (front) and posterior (back) sides of the wing?
• Answer: The side with the humerus and the feather orientation can help determine anterior vs. posterior; typically, the humerus is positioned proximally, closer to the body.

2. Removing the Skin

• Carefully cut through the skin using scissors or a scalpel, making incisions along natural separations.
• Question: Why is it important to make precise cuts when removing the skin?
• Answer: To avoid damaging underlying muscles, tendons, and bones, and to preserve tissue integrity for study.

3. Identifying Muscles

• Expose the muscles of the wing, noting their positions and sizes.
• Key muscles to locate:
• Pectoralis major: The largest muscle, responsible for the downstroke of the wing.
• Supracoracoideus: Located beneath the pectoralis, responsible for the upstroke.
• Latissimus dorsi: Extends along the side.
• Question: Which muscle is pr
