18 PRINCIPLES OP VETEEINAEY SUEGEBY 



What part of the body is mainly exposed to exuberant 

 granulations ? 



All those where the healing process is interfered with by- 

 more or less continuous irritations, as -wounds in the flexion 

 surface of the hock, pastern ; here the continuous flexion and 

 extension irritates the wound. Also in flstula of the withers 

 and saddle pressures when necrotic tissue is located at the 

 bottom of the wound, thus irritating the parts constantly; 

 also in muscular hernia, nicely seen in deep peroneal neurec- 

 tomy when the muscles protrude from an incision made into 

 its surrounding aponeurosis ; here the pinching of the parts 

 by the slit in the fascia keeps up the irritation. 



Name some other forms of abnormal granulations. 

 Torpid, irregular, weak, pale. 



What are erethistic granulations ? 



Those which bleed very easily, are dark-red and very 

 irritable and painful. 



Explain coagulation necrosis of granulation tissue. 



Following obstruction of the capillary vessels by inflam- 

 mation or their imperfect development, the wound is covered 

 with a diphtheritic-like membrane representing death of the 

 upper layers of the granulation. 



When is a cicatrization likely to become abnormal 9 



In wounds with great loss of substance cicatrization 

 becomes incomplete and the result is an ulcer, or the scar 

 shows an undue accumulation of cornified epidermic cells. 



What is a keloid ? 



A hard fibrous growth ari-injj ii a scar.
