Laryngeal Structures (Noncadaver)
To the Instructor:
One of my graduate students used an innovative method of visualizing the laryngeal structures.
With modeling clay, she developed the structures using a simple plastic soda bottle as the base
for a larynx model. This model provides students with an opportunity to see the relationships in
three dimensions and is a good activity for a lab. Following is a list of images available in the
Image Library that can be used to help with identification.
