INFLAMMATION AND WOUNDS 



207 



The following sympioms 

 may be noted in the differ- 

 ent kinds of wounds: The 

 sensitiveness to the pain re- 

 sulting from accidental or 

 operative wounds varies in 

 the different individuals and 

 species, and in the kind of 

 tissue injured. Injuries to 

 the foot, periosteum, skin 

 and mucous membrane are 

 more painful than are in- 

 juries to cartilages and ten- 

 dons. The appearance of 

 the wound varies in the dif- 

 ferent regions and the differ- 

 ent tissues. 



If the tissues are badly 

 torn or bruised, swelling 

 and sloughing may occur. 

 If the wound is transverse 

 to the muscular fibres, it 

 gaps more than when paral- 

 lel to the muscle. Wlien in- 

 fected by irritating organ- 

 isms, open and punctured 

 wounds (Fig. 58) become 

 badly swollen, discharge pus 

 freely and heal slowly with 

 excessive granulations. 

 Wounds involving tendons, 

 bursie and closed articula- 

 tions become swollen and 

 discharge synovia. Wounds
