WIKI                            DISSECTION OF THE CHICKEN WING & COMPARISON TO HUMAN ARM (COMP-ANAT)

SUMMARY:
1.  Dissection of wing (dont wait too long to dissect after getting the wing. dont freeze it either)
2.  Comparative anatomy of arm vs wing
3.  Comparative anatomy of bone structure
 
 
1.  Dissection of wing
You must have adobe reader downloaded to view and/or print this lab out. 
The basic lab is here:
dissection of the chicken wing

Follow the directions here

Take at least 3 pictures at stages of your dissection. The last one should show muscle action. 
Label the pictures to show the MAJOR bones (in red below). 

Do a google search for one more site that shows a good youtube of the dissection of a chicken wing and give the link in your wiki. 


 
2.  Comparative anatomy of arm vs wing


 
A. Phalanges
B. Manus (or hand)
C. Alula
D. Metacarpals
E. Carpal joint (or wrist)
F. Ulna
G. Radius
H. "Elbow"
I.  Humerus
J. "Shoulder" joint
In your wikibook: 

Copy the picture of the wing above.
ON THAT PICTURE, label the bones of the bird wing, A - J.  USE the names, not the letter. 
Compare the bones of the humerus and carpals in birds and humans. 
How many bones per phalanges in humans? How many metacarpals?


 
3.  Comparative anatomy of bone structure
BIRD BONE
HUMAN BONE
In your wiki 
1. describe the internal structure of the bird and human bones you see above. 
2. Why do you suppose bird bones are so hollow? 
Go here http://ltc.smm.org/histology/ and 
3. summarize what information can be gathered from 
a. bones, b. growth rates, 
c. longevities, and d. growth strategies.
