Chicken Wing Lab

Last week my class and I watched a video of someone dissecting a chicken wing.  We answered questions about the video and another website, which was really cool because you could control the chicken wing picture with your computer mouse.  Its so interesting because we learned about the biceps and triceps in a chicken wing, and how they work together.  If you pull on the bicep, the wing straightens out, but if you pull on the tricep it bends.  I liked this lab because we got to watch someone do it, instead of doing it ourselves.

List of Procedures:

  1.  Make sure you are wearing all of your safety equipment.
  2. Dry off the chicken wing because the moisture can hurt the results of the lab.
  3. Cut away the skin of the chicken. (Starting at the inner wing of the chicken, to the tip.)
  4. Under the skin is a layer of fat, blot the fat dry because it makes the chicken greasy.
  5. Remove the muscles and tendons from the chicken wing.
  6. Break one of the bones of the chicken wing.
  7. Look at the cartilage. (in bone)
  8. Clean up the place you were working at.

Here are the questions (and answers) to the lab:

  1. What is the very first step in dissecting the chicken wing?

The first step in dissecting the chicken wing is to make sure you are wearing all of your safety equipment.  

  1. What happens when you pull on the triceps muscle?

When you pull of the triceps muscle, the chicken wing points down.  

  1. What is an extensor?

An extensor is a muscle that can bend and straighten a limb (arm, leg)

  1. What happens when you pull on the biceps muscle?

When you pull on the biceps muscle, the chicken wing moves up, extending the wing.    

  1. What is a flexor?

A flexor is a muscle that bends a limb (arm, leg)

  1. What type of tissue makes up the “meat” of a chicken?

Fat, muscle, skin, biceps and triceps make up the “meat” of a chicken.  

  1. What is the function of ligaments?

Ligaments provide stability and strength in the joints of the human body.  

  1. What is the function of tendons?

Tendons connect tissue to bone.  It makes it possible for us to move, walk, etc.  

  1. What is the function of the cartilage found at a joint?

The function of cartilage found at a joint is to provide support and to be able to move the joint.  

  1. There is a yellowish tissue clumped together beneath the skin of the chicken wing. This is fat tissue, made of fat cells. What are two functions of this fat?

The fat makes the skin greasy and helps to protect the bone.  

  1. Based on your observations, EXPLAIN how and why muscles work in “opposing pairs” to move bones.

Muscles work together to move our limbs, to walk.  Muscles connect to bones which push and move our bodies.

  1. Hi Sofia!
    I really like this lab post you made. You do a great job at explaining the procedure in a clear but concise way. I also really appreciate your responses to the lab questions. I like how you included media because it made the post easy to get through.
    Thanks!
