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., 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], Small motor nerve which innervates a single pectoral suspensory muscle, the m. cucullaris.[AAO]
Cranial nerves XI and XII evolved in the common ancestor to amniotes (non-amphibian tetrapods) thus totalling twelve pairs.[well established][VHOG]
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
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]
