Lemons of the anterior horn of the spinal gray matter are liableto produce paralysis in the areas of distribution of the related nerves,without disturbance of sensibility, but with marked trophic disturbances. 35. Slight pressure upon the cord may induce moderate paral^sis(paresis) of the extensor muscles and secondary contracture of theflexors. 36. Lesions of one lateral half of the cord produce complete motorparalysis, vaso-motor disturbances, incoordination of movement, andhyperaesthesia on the corresponding side below the level of the lesion,and a loss of sensibility on the opposite side with more or less paresisin some cases. A zone of anaesthesia, surmounted by one of hyper^es-thesia, may exist at the level of the lesion on the corresponding Fig. 34.—A Diagram Designed by the Author to Illustrate the Various ChannelsThrough which a Motor Cell of the Cord may be Called into Action.—A.

Complete compression or division of the spinal cord causes anexaggeration of the reflexes of the spinal segments below the seat ofinjury on both sides; in addition to serious disturbances of motilit} andsensibilitj. 38.
