Joint Anatomy and Physiology
The Chicken Wing Dissection
Name:_________________Per.___
Background
Movement in the human body results from a series of structures that work collaboratively to provide range of
motion. Skeletal muscles, connective tissue and bones all play a significant role in movement. Joints occur
where bones articulate. Joints are classified as synovial, fibrous or cartilaginous. Synovial joints include six
different types of joints. These include ball and socket, hinge, condylar (ellipsoid), pivot, plane, and saddle
joints. In this activity you will observe the hinge joint of the wing of a chicken. It is analogous to the hinge joint
found in the human arm between the radius and ulna and the humerus.
In today’s activity you will explore the structure and function of a chicken wing and compare it to that of a
human arm. This will allow you to discover the various types of tissue involved in movement at the
macroscopic level and develop an understanding of how a particular type of synovial joint- the hinge joint
works.
Focus Questions



What are the major joint types?
How is the macroscopic structure of joints related to their function?
What are the relationships between bones, ligaments, tendons and cartilage in the human skeleton?
Procedure Part I
1. Use the PowerPoint slides to dissect the chicken wing. Make a detailed drawing to scale and include the
joint you observed, the ligaments, tendons, cartilage, bones, muscles, fat, skin and joint type.

3. Write a brief paragraph that explains how muscles, tendons, ligments, and cartilage contribute to the win’gs
movement.
4. Write a brief paragraph that compares/contrasts the human arm and the wing of the chicken.
