Location of short neck muscle motoneurons in the cat as revealed by horseradish peroxidase.
The locations of short neck muscle motoneurons have been determined by means of the horseradish peroxidase technique. Although rectus capitis dorsalis major, rectus capitis dorsalis minor and obliquus capitis caudalis muscles have different functions implicated in head movements, their motoneurons are located in a common area of the ventromedial nucleus of the spinal cord, with no noticeable somatotopic organization. The three motoneuronal populations showed similar morphometric parameters with respect to soma size and shape. Some functional implications of the findings are discussed.
