Our class was told to work on an online chicken wing lab by watching a video of other students performing the lab. However, we will be doing a lab in May on the dissection. Each part of the wing was taken apart and explained. After the video, a site explained the joints and parts of a human “wing”, or arm.
The process of dissecting a chicken wing:
- Clean out the wing, dry, put it in the tray
- Cut the upper part of the wing to the tip with a sharp utensil or scissors
- Cut out the leanest part of the wing, the muscle
- Take note of the fatty part of the chicken behind the skin
- Take note of the pink muscle
- You can now see the red blood vessels, white nerves, and tendons
- Take them out of the chicken
- Break a small bone
- Look at the bone marrow
- Look at how the ligaments work and every part of the bones
Summary of the answered questions that gave me basic facts about the lab:
When you pull on the triceps muscle of the chicken wing, the forearm moves down and extends the wing or arm. An extensor is a muscle where the contraction extends a limb. When you pull on the biceps muscle, the forearm moves up and bends the wing or arm. A flexor is a muscle whose contraction bends a limb. The muscle of the chicken is what makes the “meat” of the chicken. This is the leanest part and most edible and enjoyable part of the chicken.
The function of ligaments is that it keeps the joints stable and prevents any damage that could come about to the joints. The function of a tendon is that it is a tissue that connects the muscle to the bone. It is made up of many fibers and cells to be able to resist high tensed forces to keep the muscles to the bone safe. The function of the cartilage found at a joint is that the cartilage supports the bone, even though it is much less rigid. It allows the bones to be able to move and is more stable than muscle. The two functions of the fat in the chicken wing is that it is a shock absorber and also insulates deeper tissues.
Muscles work in opposing pairs because skeletal muscles can only contract. They need an opposite muscle to move the joint in the opposite way. Each muscle will extend the opposite joint.
