They then runupwards in the cervical sympathetic to the orbit. Thereforeocular and other symptoms maj^ be produced not only bylesions of the ascending fibres of the cervical sympathetic, butalso by lesions within the cord, affecting the fibres in theirdownward course from the medulla (this being remarkablyfrequent in syringomyelia) or b) lesions of the first two dorsalnerves or their anterior roots.
