What are the symptoms of rheum,atic m,yositis ? 



In torticollis, the cervical muscles being involved, tH© 

 neck is held to one side, all movements avoided ; palpation is 

 painful. In case the mastoido humeralis is diseased, there is 

 distinct shoulder lameness, the animal improving on exercise. 

 In pleurodynia, where the intercostal muscles are inflamed, 

 there is dyspnoea, the animal grunts when the intercostal 

 spaces are palpated, while rheumatic myositis of the lumbal 

 muscles and those of the gluteal region causes a stifiE and pain- 

 ful gait, especially painful on palpation in dogs.

 strongly recurrent and tends to chronicity. 



Online the treatment of rheumatic myositis ? 



In acute cases, warm, moist applications, later stimulating 

 applications and sodium salicylate internally. In chronic 

 cases in the horse, hypodermic injections of veratrin are indi- 

 cated. 



Rupture of Muscles. 



In what animals is the tearing of muscles mainly observed f 



Horse and ox. 

 What are the causes ? 



As a result of previous diseases, the muscular fibers may 

 have undergone granular degeneration, thus weakening the 

 m.uscle and predisposing it to spontaneous lacerations (same' 

 as seen in tendons). Direct causes are strong traction on a 

 muscle, undue and sudden unopposed contractions, blows. 

 To what extent do muscles rupture ? 



All the way from a slight tear to complete pulpification.
