However, the accessory nerve also contributes to the cervical spinal cord and spinal root through the '''foramen magnum'''; providing innervation to muscles of the neck. The spinal root of the accessory nerve branches into the '''dorsal branch''' and the '''ventral branch'''. The dorsal branch innervates the ''brachiocephalicus'', ''trapezius'' and ''omotransversarius'' muscles of the dorsal neck. The ventral branch innervates the ''sternocephalicus'' muscle.

During clinical examination any difficulties in turning the neck or muscle atrophy around the dorsal and ventral neck may indicate a problem with the accessory nerve.
