  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
 
  Trichina  \Tri*chi"na\  (-n[.a]),  n.;  pl  {Trichin[ae]}.  [NL.,  fr 
  Gr  ?  hairy,  made  of  hair,  fr  tri`x,  tricho`s,  hair.] 
  (Zo["o]l.) 
  A  small  slender  nematoid  worm  ({Trichina  spiralis})  which 
  in  the  larval  state,  is  parasitic,  often  in  immense  numbers, 
  in  the  voluntary  muscles  of  man,  the  hog,  and  many  other 
  animals.  When  insufficiently  cooked  meat  containing  the 
  larv[ae]  is  swallowed  by  man,  they  are  liberated  and  rapidly 
  become  adult,  pair,  and  the  ovoviviparous  females  produce  in 
  a  short  time  large  numbers  of  young  which  find  their  way  into 
  the  muscles,  either  directly,  or  indirectly  by  means  of  the 
  blood.  Their  presence  in  the  muscles  and  the  intestines  in 
  large  numbers  produces  trichinosis.
