 disturbed function, systemic disturbance. 



To what is the pain in afresh wound due ? 



The so-called primary wound pain, which must be differ- 

 entiated from the secondary wound pain setting in later on 

 and due to inflammatory changes, depends on the cutting 

 and tearing of sensitive nerve fibres, and the richer the 

 injured part is endowed with nerves the greater the pain. 



Are the wounds of all tissues equally painful ? 



Injury of the cranial contents, bones, cartilage, tendons 

 and connective tissue are less painful than wounds of the 

 cornea, periosteum, skin, mucous membrane (especially 

 marked when the cutting agent is dull and its action 

 delayed). 



Tp what eodent do the various animals react to pain ? 



There is a great difference, depending on the age, sex, 

 breed, species and temperament. Dogs are more sensitive 

 ■ than horses, and these more so than the ox. The individual 

 disposition also plays an important role. Thus some horses 

 can be fired without reacting perceptibly while others plunge 

 about violently. 



What hind of hemorrhages are met with in wounds ? 



1. Arterial hemorrhage : the bright red blood appears 

 in jets synchronously with the pulse beat.
