*All muscles moving the tongue are innervated by the hypoglossal nerve (CN XII)
*All muscles moving the tongue are innervated by the hypoglossal nerve ([[Nervous System - CNS - Anatomy & Physiology#Innervation - Cranial Nerves|CN XII]])
*Rostral 2/3 of tongue is innervated by the lingual branch of trigeminal (CN V) which is sensory supplying temperature, touch and pain. The Chorda tympani of facial (CN VII) supplies the taste.
*Rostral 2/3 of tongue is innervated by the lingual branch of trigeminal ([[Nervous System - CNS - Anatomy & Physiology#Innervation - Cranial Nerves|CN V]]) which is sensory supplying temperature, touch and pain. The Chorda tympani of facial ([[Nervous System - CNS - Anatomy & Physiology#Innervation - Cranial Nerves|CN II]]) supplies the taste.
*The caudal 1/3 of tongue is innervated by the glossopharyngeal ([[Nervous System - CNS - Anatomy & Physiology#Innervation - Cranial Nerves|CN IX]]) providing motor function for taste.
