Surgical exposure in the right neck of a rabbit (magnification 3×). The main trunk of the hypoglossal nerve (CN XII) is noted, as is its relationship to the greater horn (cornu) of the hyoid bone. Also shown is a 0.75-mm electrode wrapped around the medial branch of the hypoglossal nerve as it moves anteriorly (rostrally) to innervate the genioglossus muscle. The 1.0-mm cuff has not yet been placed around the main trunk of the nerve.
