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. muscles usually act in groups.

Dissection Kit Tray Chicken Wing Gloves Material

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). Bad Picture! This is a picture of his hand, not the chicken wing. hand Good Labels!!

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

Procedure Step 3 The end of the muscle is at the tip of the bone.

Procedure Step 4 The left top muscle was the bicep and the lower right muscle is the tricep.

Procedure Step 5 The bottom left is the extensor digitorum. The right side is called abductor pollicus longorus.

Procedure Step 6 The fat is the white gelatinous

Procedure step 7 The white line within the muscle are the tendons and the stretched white in the elbow is also one.

Procedure step 8 The inside elbow has a ligament to it.

Procedure step 9 The top white layer above the bone is cartilage.

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.

Procedure step 11 Clean 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.

Questions: (hint hint!write them in your notebook!!!) 1. What function is performed by ligaments?the Ligaments have the job of flexing and What is the function of a tendon? the function of the ligaments are to flex the muscle and reflex it, The function for the tendons are the separate pieces of the ligament that are in direct contact with the muscles. 2. What is more proximal, the insertion or the origin for the attachment of the muscles in the chicken wing? the origin is more proximal to the body. 3. What tissue is referred to when one speaks of the “meat” of the chicken? they are talking about the muscle in general. 4. Name the two main types of movement that occur when a wing is raised and lowered in flight? the two types of movement are called flex and reflex. 5. What bone in the wing is connected to the chicken’s body at the shoulder? it is the humerus, which is attached to the humeral head then the scapula. 6. Name the two bones found in the forearm of the wing? The radius and the ulna. 7. What type of joint connects the wing to the body? it’s a ball and socket joint. 8. What type of joint moves the wing at the elbow? it’s a fixed joint where it only moves in two directions. 9. The muscle you observed is classified as what type of muscle tissue? the bone we observed is classified as skeletal muscle.
