-* 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.
