title: Morphology and distribution of the motor neurons of the accessory nerve (nXI) in the Japanese toad: a cobaltic lysine study.
abstract: Motoneurons supplying the accessory nerve (nXI) of the Japanese toad were retrogradely labelled by applying the cobaltic lysine to the cut end of the nerve. They had morphological characteristics and a distribution pattern similar to those of the rostral spinal motoneurons rather than the branchial motoneurons. We propose that the anuran nXI is equivalent to the so-called spinal portion of the nXI of other vertebrates, and both should be regarded as part of the rostral spinal nerves rather than the nerve accessory to the vagus nerve.
