Give some examples of degenerative atrophy. 



Atrophy of the spinatus muscles follows paralysis of the 

 suprascapular nerve ; paralysis of the radial nerve leads t6 

 wasting of the triceps extensor of the forearm. Paralysis of 

 the recurrent laryngeal nerve in some instances causes 

 arytenoid hemiplegia and atrophy (roaring), while in the 

 hindleg paralysis of the crural nerve produces atrophy of the 

 triceps femoris. Atrophy of muscles due to inflammatory 

 processes producing serious nutritive disturbance find their 

 best example in azoturia (hemoglobinuria). 



LIPOMATOUS ATROPHY. 



What do you understand by lipomatous atrophy ? 



This is the only form of atrophy where the volume of the 

 muscle increases in size, explained as follows : In the connec- 

 tive tissue between the primitive muscular fibers an excessive 

 amount of adipose tissue develops, which, by its pressure, 

 leads to atrophy of the contractile substance. It is the large 

 amount of fat thus formed which increases the size of the 

 muscle, while in reality the muscular elements proper are 

 being more or less destroyed. 



Give an example of lipomatous atrophy, . 



Commonly seen in animals fattened for the market. It 

 is a well known fact that fat pigs or cattle are unable to stand 

 any exertion, simply due to the depraved state of the muscu- 

 lar system. 



Outline the treatment of muscular atrophy. 



In simple atrophy a nourishing diet with regular work, 

 hand rubbing and possibly stimulating applications or injec- 

 tions of strychnine or veratrine are indicated. In degenera- 

 tive atrophy the contractile substance is destroyed and not
