Pamela Figus Lab 8: Chicken Muscle Dissection Purpose To determine the musculoskeletal comparisons of chicken wing to human upper extremity. Hypothesis The muscles and tendons of the chicken wing will react in the same manner as that of a human upper extremity. Materials & Methods Materials: List your materials used for your lab here. Methods: Part A: Arrange your wing so that the joints match the image below. Remove the skin as follows: At the cut end of the upper wing, slip the tip of the scissors between the skin and the muscles underneath. Cut the skin lengthwise, to the joint between the upper wing and the lower wing. Using scalpel and scissors carefully remove the skin from the joint between the upper and lower wing. Be careful not to cut any muscle, tendons or ligaments. Remove the skin of the lower wing in the same way that you removed the skin from the upper wing. Leave the skin on the wing tip. Using scissors, remove any tissues covering the muscle. Use a blunt probe to separate the individual muscles from each other without tearing them. Label the following structures of your specimen: Bicep muscle Tricep muscle Forearm muscle Tendon Part B: Straighten the chicken wing and hold it horizontally above the tray. Identify the biceps muscle and triceps muscle. The biceps muscle is on the anterior part of the upper wing; the triceps is located on the posterior part of the upper wing. Pull on each of the muscles in the upper and lower wing, and note the movement that each muscle causes. Turn the wing upside down and bend the joints. Again pull on each muscle and note how the bones move. Locate the nerve and blood vessels along the biceps muscle. Locate where the biceps muscle attaches to the bones. Pull on the muscle again and try to recognize what is happening to the bones. Part C: Write your name three
