Cranial nerve that innervates the sternocleidomastoid and trapezius complex of muscles. [Bemis_WE, Functional_Anatomy_of_the_Vertebrates:_An_Evolutionary_Perspective, Glossary_G-1, Grande_L, Liem_KF, Third_Edition_(2001)_Orlando_Fla.:_Harcourt_College_Publishers, Walker_WF][VHOG] A small motor nerve which emerges from the lateral wall of the medulla with the roots of the vagus nerve, and innervates a single pectoral suspensory muscle, the m.cucullaris. Small motor nerve which innervates a single pectoral suspensory muscle, the m. cucullaris.[AAO] |

| external_ontology_notes |
FMA has distinct cranial and spinal parts - WP says 'Traditional descriptions of the accessory nerve divide it into two parts: a spinal part and a cranial part.[1] However, because the cranial component rapidly joins the vagus nerve, becoming an integral part of said nerve, modern descriptions often consider the cranial component to be part of the vagus nerve and not part of the accessory nerve proper.[2] |

In mice, the spinal branch of this motor nerve innervates the trapezius and the sternocleidomastoid muscles. The cranial branch joins the vagus nerve and innervates the same targets as the vagus nerve |
