42 THE VETERINARY SCIENCE 



spinal cord, to about opposite the hip bones, is another set 

 of nerves, one of which goes to supply the rectum, or back 

 bowel; this gives the power of passing manure. Others go 

 to the womb and bladder ; these assist in urinating by con- 

 tracting the bladder. Other nerves pass to the small organs 

 situated in the pelvic cavity; some of these nerves pass down 

 to the hind legs, supplying them with nervous power. The 

 remainder of the nerves of the spinal cord go to supply the 

 tail. 



Nerves have the appearance of bunches of white thread 

 held together by connective tissue.
