PARALYSIS 



- -- '--*C ^^i^P^^ -'F "*' 



Hog suffering from paralysis of liiiul limbs 



Paralysis, or loss of motion in a part, may be due to a lesion 

 of the brain, of the spinal cord, or of a nerve. It may also be caused 

 by reflex irritation. When the paralysis affects both sides of the 

 body, posterior to a point, it is further designated by the name 

 parapelgia. When one side of the body (a lateral half) is paralyzed, 

 the term hemiplegia is applied to the affection. When paralysis 

 is caused by a lesion of a nerve, the paralysis is confined to the par- 

 ticular part supplied by the afifected nerve. 



Paralysis may be due to concussion of the spine, fracture of a 

 bone of the spinal column with consequent compression of the 

 spinal cord, concussion of the brain, or compression of the brain. 

 An injury to one side of the brain may produce paralysis of the 

 same side of the head, and of the opposite side of the body, hemi- 

 plegia. Paralysis may occur in connection with parturient apoplex}-. 

 lead poisoning, ergotism, etc.
