Dissecting with Emily - Canada goose gizzard (ventriculus)

Here's a quick iPhone video of the stomach region of a Canada goose. The dissection was done by Emily Caggiano, an Ohio University Honors Tutorial College student working in our lab. It's interesting because it shows how a large-bodied avian herbivore "chews" tough plant material without a set of teeth in its jaws. The vid is kinda gross so be warned. It shows the esophagus and proventriculus (glandular part of the ventriculus) leading into the huge muscular gizzard (the muscular part of the ventriculus) which then leads out the pyloric area to the duodenum. Check out the keratinous cuticular plates that help grind up the food, along with the grit and small stones (that we had washed out).
