[1] Remove the skin from the wing, it is easiest to use your fingers and the technique demonstrated on the video, this is called blunt dissection because no blade is involved. -Your fingers give you very good control over moving the skin away from the muscle deep to the skin. -You can use the scissors or razor blade if needed. [2] Once the skin is removed examine the organization of the muscles and the bone. -Locate tendons and identify and blood vessels and/or nerves you see. *Take a picture of the skinned wing before you begin to work the muscles. (See video) (1 point) [3] Locate the triceps brachii and biceps brachii on the wing (see video). *Lift the wing, as demonstrated in the video, and gently pull on the biceps – what happens?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
