AIM
To observe the complex hinge joint in a chicken wing.
HOW DOES IT WORK?
Time allocation: 45 Min
As the layers of muscle, skin and other soft tissue are dissected away from the joint, the various anatomical structures can be identified. Once dissection has been completed the joint can be manipulated to move in various ways illustrating the nature in which the joint moves and the structures that limit its movement.
APPARATUS:
- Dissecting tray
- Dissecting kit
- Disinfectant
- Paper towels
- Latex gloves
Supplied By Educator:
- Chicken wings (raw is preferable)
METHOD:
- Place the wing on the dissecting tray. Using forceps and a scalpel, carefully remove the skin from the chicken wing.
- Remove the yellow adipose (fat) tissue from the wing and the semi-transparent connective tissue that surrounds the skeletal muscles.
- Identify the white tendons that attach the muscle to the bones.
- Cut through the head (epiphysis) of one of the long bones and observe the spongy bone tissue.
- Look for the ligaments that join the long bones.
- Identify the cartilage at the ends of the long bones.
- Wash all the surfaces, apparatus and your hand thoroughly after dissection
CONCLUSION
The following should be observed:
PRECAUTIONS:
- Disinfectant is very important, make sure you have access to soap and water so that you can sanitize your hands before, after and while you are working with meat.
- Raw chicken may contain Salmonella spp. Which can cause severe food poisoning it is important to work in a sanitary environment and to clean the surfaces used after dissection. Scalpel blades and dissection tools must be sterilized afterwards and chicken to be disposed of afterwards. The remains of the dissection must not be consumed.
