changes is apt to occupy the whole extent of the transverse section 

 {transverse spinal palsy). 



Inhibition of the motor centres may also be caused by exces- 

 sive stimulation of the sensory nerves in a reflex manner (so- 

 called reflex paralysis or neurolytic palsy), as where complete 

 paralysis of the posteripr part of the body occurs after forcible 

 compression of the kidney, bladder, ureter or a portion of the 

 bowel (Samuel). 



Results and terminations of palsies. The results of motor loss 

 vary with the duration, extent of disturbance, the importance

of the affected muscles and of the causative lesion. In paralysis 

 of the heart and respiratory muscles death at once ensues from 

 cessation of circulation and gas interchange. Indirectly palsies 

 of the pharyngeal muscles, the bladder, the intestine or the 

 extremities may result in death because of the development of 

 various possible complications (aspiration of fluid in the air 

 passages causing aspiration pneumonia ; retention of urine and 

 fecal material with production of dilatation, inflammation and 

 erosion of the mucous membrane : hypostases and decubitus with 

 blood poisoning, etc.). In case of paresis of the sphincter of the 

 bladder the urine constantly dribbles and the same symptom con-
