Each of the twelfth pair of cranial nerves, supplying the muscles of the tongue.
- ‘Descendens hypoglossi may be carried partly or completely by the vagus nerve instead of the hypoglossal nerve.’
- ‘Fibers of the hypoglossal nerve take a ventrolateral course and emerge between the olive and pyramid.’
- ‘The hypoglossal nerve has been reported to carry sensory fibers which supply the tip of the tongue.’
- ‘The ipsilateral hypoglossal nerve was sectioned, and that half of the muscle became silent.’
- ‘Some fibers of the hypoglossal nerve can be traced through the reticular formation as they course towards the ventrolateral sulcus.’
