Chicken Wing Dissection
Equipment
• scalpel: cuts through tissue
• forceps:
moves tissue aside
(tweezers)
• dissecting needle:
separates connective tissue
Equipment
• scissors:
cuts through skin once scalpel

without damaging them
Chicken Wing – External Features
Chicken Wing Dissection
Chicken Wing - Removing the Skin
Chicken Wing - Muscles
When the skin is removed you can see
the muscles of the wing and how each
one is attached to the skeleton.
Run the forceps along the length of each
muscle until you reach the tendon. The
tendon is the white, tough, fibrous material
that connects the muscle to the bone.
Chicken Wing - Bones
Elbow Joint - Showing Ligaments
Note:
Ligaments
connect bones
together.
At the surface
of each bone
forming the
joint is a white,
shiny,
slippery
substance
called cartilage.
Chicken Wing – Dissection
Instructions:
1. Follow the procedure on your handout.
(steps 1 – 13)
2. As you follow each step, answer any questions
(compare, describe, draw, etc.) that you
encounter in the procedure.
(3, 4, 6, 7, 8, 9, 10, 11, 12)
3. Do Analyze and Evaluate questions a – e.
Hand in one per pair.
The chicken wing and the human hand are very
similar. It clearly shows evolutionary links.
Match the chicken
wing parts shown
on the diagram
with the equivalent
human part.
