Can you find the ligaments that hold the bones together?.Did you notice that the muscles that move the lower wing are in the upper wing? Where are the muscles that control the upper wing in the chicken?.Can you find the cartilage at the joint between the humerus and radius/ulna?.Note the points at which these muscles attach to the bone, and carefully remove them one by one.Note that these muscles are in opposition to each other.Locate the two muscle bundles that bend and straighten the lower section of the wing, below the elbow joint, by pulling on each muscle in turn.The "alula" is the equivalent of what part of your hand?.The elbow joint is labelled in this figure."Manus" is derived from the same word root as "manual." What is the equivalent part on your body?.Blot dry any fat with a paper towel, and remove it to expose the underlying anatomy.Be careful not to cut the muscles, ligaments, and tendons.
#ALULA WING SKIN#
Using the scissors, remove as much of the skin as you can, cutting along the line of the bones.Note the locations where the feathers were inserted into the skin.Ĭhicken wing with skin and muscle attached.Use your fingers to feel the bones and muscle bundles beneath the skin.Note the directions in which the joints bend.Note the locations of the joints where the wing bends.Holding the wing at the shoulder and wing tip, fully extend the wing.Discard the chicken wing and parts at the end of this exercise.Wash all equipment in hot soapy water when done.To reduce the chance of jabbing or cutting yourself, the only tools you will need are scissors and tweezers.You may use rubber gloves if desired, or bare hands if you prefer.Since you will be handling raw chicken, which may have germs on the surface, please wash your hands with soap and water before and after this procedure.What predictions can you make before seeing the internal anatomy?Ĭhicken Wing Anatomy: Watch the following video as a general guide to the procedure. See if you can find a similar image of a dolphin or whale flipper for another comparison. However, the bird "hand" is reduced, whereas the bat and human hand have more in common. You might think that the two wings would be more similar in design because of the job they do but, in fact, the bird wing and human arm are more similar on the interior. The color coding shows the way the bony elements were modified in each species. The vertebrate forelimb of human, bird, and bat may not appear to have much in common, but a closer examination of the anatomy shows that the same bones were applied to a variety of different jobs in each of these species.
