How do you test the hypoglossal cranial nerve?

In a normal person the protruded tongue lies in the midline. The hypoglossal nerve can be damaged at the hypoglossal nucleus (nuclear), above the hypoglossal nucleus (supranuclear), or interrupted at the motor axons (infranuclear). Hypoglossal nerve stimulation is used to manage moderate to severe obstructive sleep apnea. 1. The cranial nerve assessment is an important part of the neurologic exam, as cranial nerves can often correlate with serious neurologic pathology. The impulses for movement are carried by nerves known as upper motor neurons (UMN). Stimulating lead This lead is placed around the medial branches of the hypoglossal nerve (discussed below) and initiates contraction of the tongue muscles thus opening the upper airway.
