accessory nerve morphogenesis
The process in which the anatomical structure of the accessory nerve is generated and organized. 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.
