Step 1:Use scissors to cut the skinas shown .Try not to cut through the muscles located beneath the skin
Procedure Step 2 Remove as much skin from the thickest part of the wing as possible, exposing the underlying muscle Observe the muscle. The muscles are bundles of pale pink tissue that surround the bone.
Procedure Step 3 • Find the two groups of muscles in the upper arm. (you know these names!! ) • Hold the arm down at the shoulder, and alternately pull on each muscle group. • Observe what happens.
Procedure 4 • Note any yellow tissue found in small clumps on the inside of the skin. This is a type of connective tissue called fat.
Procedure step 6 • Remove any remaining skin from the elbow joint. • Locate a tendon. Tendons are shiny white tissues at the ends of the muscles that attach muscles to bones.
Procedure step 7 • Locate a ligament. Ligaments are shiny white tissue at the ends of bone.
