  1. Chicken Wing Dissection • Copy this Power point onto your desktop. • Edit your saved Desktop version. • Each photograph needs to include an approved marker to assure authenticity.

  2. Work as a team! Research, Photograph, Dissect, Produce the Power Point. Everyone is to be busy! Do not plan on washing your hands until the end of the dissection has been announced by the instructor.

  3. Red words are requirements. Replace with your own info. Do not change backgrounds or font styles.(Leave the black letters on slide)Chicken Wing Dissection Insert Names of GroupGroup Number (green words= suggestions) add picture of studentsPractice Saving now!Save to Network Neighborhood, Entire Network, Library, D501, period__.

  4. Background Put red information into a clean bulleted form:Certain principles of muscle function help us to understand bone-muscle relationships. First, skeletal muscle contracts only if it is stimulated by the nervous system. Second, skeletal muscles usually produce movements by pulling on bones across joints. The bones serve as levers and the joints serve as fulcrums. Third, muscles usually lie next to the bones they move. And, finally, muscles usually act in groups. Add pictureAdd more slides if necessaryThere is a lab book version of this exercise at: http://www.pghs.org/science/rubin/anatomy/chicken%20wing%20dissection.htm

  5. Procedure Step 1 • Carefully extend the wing to find out how many major parts it has. • Include a photo of the external structure. Label: upper arm, elbow, lower arm, and hand. (wing tip). hand Bad Picture! This is a picture of his hand, not the chicken wing. Good Labels!!

  6. Procedure Step 2Use scissors to cut the skinas shown .Try not to cut through the muscles located beneath the skin

  7. Procedure Step 3 Remove as much skin from the thickest part of the wing as possible, exposing the underlying muscleObserve the muscle. The muscles are bundles of pale pink tissue that surround the bone. • Include Photo with labels!!!

  8. Procedure Step 4 • Find and photograph the two groups of muscles in the upper arm. (you know these names!! Label them!!) • Hold the arm down at the shoulder, and alternately pull on each muscle group. • Observe what happens. Record(photo!).

  9. Procedure Step 5 • Photograph the two groups of muscles in the lower arm (you know these names! Label them!). • Hold the arm down at the elbow and alternately pull on each muscle group. Illustrate what happens.

  10. Procedure Step 6 • Photograph any yellow tissue found in small clumps on the inside of the skin. This is a type of connective tissue called fat.Label the fat

  11. Procedure step 7 • Remove any remaining skin from the elbow joint. • Locate,photograph and label a tendon. Tendons are shiny white tissues at the ends of the muscles that attach muscles to bones.

  12. Procedure step 8 • Locate, photograph and label a ligament. Ligaments are shiny white tissue at the ends of bone.

  13. Procedure step 9 • Locate, photograph and label cartilage. Cartilage is the slippery shiny white tissue at the ends of bone.

  14. Procedure step 10 • Once you have identified the following parts: skin, muscle, tendon, ligament, cartilage and bone, call your instructor over for a group oral quiz and initials.

  15. Procedure step 11Clean UP!!! • Throw away all chicken wing parts into the designated garbage can. • Put dissection tools into beaker of soapy water. Stack tray next to beaker. Wash your hands thoroughly with soap and water.

  16. Questions: (hint hint!write them in your notebook!!!) 1.What function is performed by ligaments?_________________________________________ What is the function of a tendon? ________________________________________________ 2.What is more proximal, the insertion or the origin for the attachment of the muscles in the chicken wing? 3.What tissue is referred to when one speaks of the “meat” of the chicken? 4.Name the two main types of movement that occur when a wing is raised and lowered in flight. 5. What bone in the wing is connected to the chicken’s body at the shoulder? ____________________ 6.Name the two bones found in the forearm of the wing. ________________ _____________________ 7.What type of joint connects the wing to the body? _______________________________________ 8.What type of joint moves the wing at the elbow? 9.The muscle you observed is classified as what type of muscle tissue? ____________________________
