The anatomy of the equine guttural pouches is extremely difficult to master. This may be due to the complexity of this area of the horse’s head and neck region, or because it is difficult to envision the pouches, where they are located, and how they are related to the cranial nerves and blood vessels in that area. This interactive book was created to help overcome these difficulties by providing 3-D models, interactive images, endoscopic images and videos, and simulated endoscopic views that the viewer can control.
