Chicken wing Dissection

Which muslces need to contract to extend the wing?

I believe it is the tricep and the ulna.

Does the suface feel smooth? what other observations can you make about the chicken wing compered to a human arm?

The surface feels smooth because the joints have to move and the bones Intact with the muscles so they have to be smooth. the muscle system that moves the chicken wing is very similar to that of a chickens.

Write a paragraph to describe how the components of the chicken wing function together. Use terminology.

the bones make the wing of the chicken strong and stable. the muscles like the tricep and the bicep apply power to the wing so that the wing can allow the creature to move and should make the chicken fly (however due to the fact of evolution and probably human intervention the chicken is to heavy to fly). the joints allow the chicken wing to move around smoothly.

Identify the similarities and differences that can be observed between a chicken wing and a human arm.

for the most part the chicken wing and the human arm are nearly identical the bicep and tricep is the same, the bone structure is strikingly similar. The only difference I can tell is that there is a muscle or tendon connecting from the shoulder to the wrist and the fingers on where the hand should be are fused to be stronger.

Suggest how is the chicken wing structure adapted for flight.

the muscle connecting the shoulder to the wrist provides stability and makes the wing stronger and more secure.

Suggest how the human arm structure adapted for lifting objects.

the human arm is built like a 3 class lever the elbow is the fulcrum, the bicep and the tricep is the force and the forearm is the lever.
