Chicken Wing Dissection There are 600 different muscles in the human body, and an astounding 6 trillion individual fibers. The largest muscle is the gluteus maximus (found on buttocks) and the smallest is the stapedius, which is located in the ear. Contrary to popular belief, muscles are not made up of mostly protein. In fact, they are only 20% protein, and the rest is mainly water mass. Most animal muscle tissue is similar, including aves or birds. Today you will examine a chicken wing and understand its general make up, including parts and location. Purpose: To understand the location and function of muscles, bones, and tendons. Materials: gloves, raw chicken wing, dissecting tray, paper towels, forceps, scissors, scalpel, disinfectant Procedure: 1. Have “material maintenance” person collect all materials except raw chicken. 2. Have your “surgeon” put on gloves and get the raw chicken from your teacher. CAUTION: DO NOT TOUCH YOUR FACE WITH YOUR HANDS DURING THE LAB. Also be careful with the sharp objects. 3. Place the chicken wing on a paper towel in your dissecting tray. Peel back or cut away the skin and fat of the largest wing segment to expose the large muscle. This muscle is called the biceps. Find the tendon that attaches the bicep to the bones of the middle segment of the wing. Tendons are tough, shiny white cords that join the muscle to the bone. 4. Use forceps to pull on the tendon of the biceps, and observe what happens to the chicken wing. 5. Use scalpel or scissors to remove all muscle from the wing. Try to crack the bone in half and observe what is inside. BE BAREFUL CONTENTS MAY FLY. 6. Dispose of chicken. Clean ALL tools and tray
