Title: Motor organization of the spinal accessory nerve in the monkey. Author: Jenny A, Smith J, Decker J. Journal: Brain Res; 1988 Feb 16; 441(1-2):352-6. PubMed ID: 2451984. Abstract: The segmental and topographical organization of motoneurons of the spinal accessory nerve was studied in monkeys with horseradish peroxidase (HRP). The sternomastoid muscle is innervated primarily from the C1-C2 level of the cord and the motor column is medial in the ventral horn. The trapezius muscle, however, is innervated primarily from the C2-C3-C4 levels of the cord and the motor column lies in the ventrolateral region of the ventral horn. The data are discussed with regard to treatment of torticollis.[Abstract] [Full Text] [Related] [New Search]
