===Hypoglossal nerve (XII)===
===Hypoglossal nerve (XII)===
The hypoglossal nerve is part of the group of cranial nerves responsible for the control of muscles of the head. It is in part a cervical nerve due to its caudal position on the [[Hindbrain_-_Anatomy_%26_Physiology|brain stem]]. The nerve is composed of '''general somatic efferent fibres''' which control the intrisic and exterinsic muscles of the tongue (together with other nerves including the lingual nerve, facial nerve, lingual branch of the glossopharyngeal nerve and the vagus nerve). The nuclei of the nerve is located within the medulla oblongata of the brain stem and it passes through the '''hypoglossal canal'''.
