• Work as a team! Research, Photograph, Dissect,
  Produce the Power Point. Everyone is to be busy!
• Do not plan on washing your hands until the end
  of the dissection has been announced by the
  instructor.

Background

• Put red information into a clean bulleted
  formCertain principles of muscle function help
  us to understand bone-muscle relationships.
  First, skeletal muscle contracts only if it is
  stimulated by the nervous system. Second,
  skeletal muscles usually produce movements by
  pulling on bones across joints. The bones serve
  as levers and the joints serve as fulcrums.
  Third, muscles usually lie next to the bones they
  move. And, finally, muscles usually act in
  groups.

Procedure Step 1

• Carefully extend the wing to find out how many
  major parts it has.
• Include a photo of the external structure.
  Label upper arm, elbow, lower arm, and hand.
  (wing tip).

Bad Picture! This is a picture of his hand, not
the chicken wing.
Good Labels!!

 Procedure Step 2 Use scissors to cut the skin
as shown .Try not to cut through the muscles
located beneath the skin

8
Procedure Step 3

• Remove as much skin from the thickest part of the
  wing as possible, exposing the underlying muscle
  Observe the muscle. The muscles are bundles of
  pale pink tissue that surround the bone.
• Include Photo with labels!!!

9
Procedure Step 4

• Find and photograph the two groups of muscles in
  the upper arm. (you know these names!! Label
  them!!)
• Hold the arm down at the shoulder, and
  alternately pull on each muscle group.
• Observe what happens. Record(photo!).

10
Procedure Step 5

• Photograph the two groups of muscles in the lower
  arm (you know these names! Label them!).
• Hold the arm down at the elbow and alternately
  pull on each muscle group. Illustrate what
  happens.

11
Procedure Step 6

• Photograph any yellow tissue found in small
  clumps on the inside of the skin. This is a type
  of connective tissue called fat. Label the fat

12
Procedure step 7

• Remove any remaining skin from the elbow joint.
• Locate,photograph and label a tendon. Tendons
  are shiny white tissues at the ends of the
  muscles that attach muscles to bones.

13
Procedure step 8

• Locate, photograph and label a ligament.
  Ligaments are shiny white tissue at the ends of
  bone.

14
Procedure step 9

• Locate, photograph and label cartilage.
  Cartilage is the slippery shiny white tissue at
  the ends of bone.

15
Procedure step 10

• Once you have identified the following parts
  skin, muscle, tendon, ligament, cartilage and
  bone, call your instructor over for a group oral
  quiz and initials.

16
Procedure step 11Clean UP!!!

• Throw away all chicken wing parts into the
  designated garbage can.
• Put dissection tools into beaker of soapy water.
  Stack tray next to beaker.
•         Wash your hands thoroughly with soap and
  water.

•  
• 4.       Name the two main types of movement that
  occur when a wing is raised and lowered in
  flight.
•  
•  
• 5. What bone in the wing is connected to the
  chickens body at the shoulder? __________________
  __
•  
• 6.       Name the two bones found in the forearm
  of the wing. ________________ ____________________
  _
•

•  
• 8.       What type of joint moves the wing at the
  elbow?
