* The hypoglossal nerve, CN XII provides motor innervation to the [[Tongue - Anatomy & Physiology|tongue]].
* Normally, a horse resists the [[Tongue - Anatomy & Physiology|tongue]] being retracted from the mouth.
** The horse will quickly return the tongue after it is pulled out to the side.
* Horses with hypoglossal weakness appear differently.
** The [[Tongue - Anatomy & Physiology|tongue]] may protrude from the mouth.
** Chronic unilateral hypoglossal lesions may result in unilateral tongue atrophy.
** Bilateral hypoglossal lesions may result in difficulty prehending food.
* Horses with cerebral dysfunction may have signs corresponding to tongue weakness.
** However, [[Tongue - Anatomy & Physiology|tongue]] atrophy is not present in these animals.
