====Variations====
  *Compare a fresh wing to a previously simmered and cleaned wing to highlight joint shapes and hand bones.
  *Test mechanical advantage by measuring force needed to flex the elbow when pulling tendons at different distances from the joint.
  *Dissect a chicken leg next and compare femur tibia fibula to humerus radius ulna to discuss limb homology.
  *Use thread loops on multiple tendons to coordinate finger like movements of the wing tip for a demonstration model.
  *Contrast wing anatomy with a human arm model or diagram to map homologous structures.



====Safety Precautions====
  *Wear disposable gloves and lab coat; wash hands thoroughly after the activity.
  *Handle blades and shears carefully; cut away from fingers and body; keep tools on a stable cutting surface.
  *Treat raw poultry as a potential source of pathogens; avoid touching face; keep separate from foods and kitchen items used for eating.
  *Disinfect benches, tools, and trays after use; do not reuse household utensils for food preparation unless they have been thoroughly sanitized.
  *Dispose of tissues, skins, and contaminated towels in sealed trash according to local waste rules.
  *If simmering to clean bones, use dedicated cookware, avoid splashes, and allow components to cool before handling.





====Questions to Consider====
  *Which muscles flex and extend the elbow, and how can you tell? (The anterior muscle pulls to flex and the posterior muscle pulls to extend; pulling their tendons produces these motions.)
  *What is the difference between a tendon and a ligament? (Tendons connect muscle to bone; ligaments connect bone to bone across a joint.)
  *What fluid and tissue reduce friction inside the joint? (Synovial fluid and articular cartilage.)
  *How is the wing an analog for the human arm? (Both have a single proximal bone and two forearm bones with similar muscle group functions, indicating homologous limb structure.)
  *Where do you find spongy bone and where do you find marrow? (Spongy bone in the epiphyses near joint ends; marrow in the medullary canal of the shaft.)
  *Why does a dull blade often work better than a sharp scalpel for skin removal in this activity? (A dull blade separates along natural tissue planes without cutting underlying fascia and muscles as easily.)
  *What motion occurs at the elbow joint and what prevents dislocation during normal movement? (Hinge like flexion and extension; the joint capsule and ligaments stabilize the bones.)
