In Science we recently dissected a chicken wing. I was more comfortable with dissecting the chicken wing (removing skin, muscles, tendons, ligaments) than what I expected.

I used collaboration, communication, and organisation skills to successfully complete this dissection. For collaboration I worked with my partner in sections to remove the parts in the chicken wing. For communication, I talked with my partner about where to remove and where to keep in the chicken wing, and if any of us got uncomfortable, to reassure them and to let the go take a break, and continue the dissection while informing them when they arrive. I used organisation skills to make neat piles of the skin, muscles and tendons, and to also follow the instructions by order.

Here are some process pictures and time lapse of the skin removal process.

Observations :

I noticed when I extended the chicken wing out (our chicken wing was not very flexible) I could see the bicep ,extending and the tricep contracting. I also noticed that a chicken’s skin is bumpy (and slippery), similar to a goose, which explains why the bumps on your arm when the temperature lowers, is called goose bumps. The chicken wing is similar to the human arm, as we have triceps and biceps, a humerus, both the radius and the ulna on the lower arm, and a shoulder joint and elbow joint.

One quite apparent difference is the tip of the wing, in our case, we have hands, to grip onto things, like if we were to lift weights. In the chickens case, they have a metacarpus, but not a carpus, and their phalanges is used to attach feathers, instead of having fingers. We also do not have a very long tendon that extends from the shoulder to the end of the radius and ulna. That helps the wind catch in the skin between the bone and the tendon, so the chicken can fly (also feathers). But, we all know that chickens cannot fly for long periods of time, one thing that might affect their flight is their weight, pulling them down. For example, our chicken had many fat glands in the wing, and big muscles which is the main source of weight to a chicken.

In conclusion,  humans and chickens have a very similar bone structure and muscle group, but each is modified to be slightly different from one another.
