* The pharynx and larynx are innervated by:
** CN IX - the glossopharyngeal nerve
** CN X - the vagus nerve
** CN XI - the accessory nerve
* Pharyngeal and laryngeal function is best studied by:
*# Observing the horse eat and swallow
*# Endoscopy
====Laryngeal Dysfunction====
* Left recurrent laryngeal hemiplegia is the most common dysfunction in horses.
** The left recurrent laryngeal nerve is a branch of the vagus nerve.
** Horses are known as "roarers".
====Pharyngeal Dysfunction====
* Pharyngeal paralysis in horses is commonly associated with peripheral disease.
** Especially guttural pouch disease.
*** Endoscopy of the guttural pouches should be therefore be performed in horses that are dysphagic.
