Chicken Wing Dissection
Objectives: After dissection of the mink muscular system it is nice to see
the muscular system of other organisms. Today we will be dissecting the
wing of a chicken. You will be observing the actual muscles, tendons,
ligaments, bone and cartilage. Additionally, you can observe the movement
of opposing pairs of muscles.
1. Draw your chicken wing as is:
2. At the end of the upper wing, slip the tip of the scissors between the
skin and the muscles underneath.
a. What skin layer are you under?
3. Cut the skin lengthwise and dissect completely from your wing.
4. Sketch your skinless chicken wing here:
5. Use a blunt probe to separate the individual muscles from each other
without tearing them. Sketch the wing now with the separated muscles
indicated.
6. Straighten the chicken wing and hold it horizontally above the tray.
Pull on each of the muscles and note the movement that each muscle
causes. Describe what happens here. (use a diagram if it helps)
7. A tendon is connective tissue that connects muscle to bone. Once you
find one, draw it in detail here.
8. A flexor is a muscle that shortens the distance between two bones (at
the joint). Find a flexor muscle and cut it in the middle of the muscle
belly. Now try to move your wing. Describe what happened (or
didn’t happen) here.
9. An extensor is a muscle that increases the angle between two bones.
Find an extensor muscle on your wing and cut it in the middle of the
muscle belly. What happens to the wings ability to move?
10.Name a muscle that flexes and extends the bones on your body?
Explain what the muscles are and where the movement is occurring
(be specific).
11.Dissect out the two bones of the lower limb and the one bone of the
upper limp completely. If you can, try to keep the cartilage at the
ends and the joints intact. Sketch the dissected bones out here and
identify all bones in your diagram.
12.Use a dissecting microscope to zoom in closely at the joint. What is
the joint you are looking at?
