  Gland  \Gland\,  n.  [F.  glande,  L.  glans,  glandis,  acorn;  akin  to 
  Gr  ?  for  ?,  and  ?  to  cast,  throw,  the  acorn  being  the

  1.  (Anat.) 
  a  An  organ  for  secreting  something  to  be  used  in  or 
  eliminated  from  the  body;  as  the  sebaceous  glands  of 
  the  skin;  the  salivary  glands  of  the  mouth. 
  b  An  organ  or  part  which  resembles  a  secreting,  or  true, 
  gland,  as  the  ductless,  lymphatic,  pineal,  and 
  pituitary  glands,  the  functions  of  which  are  very 
  imperfectly  known 
 
  Note:  The  true  secreting  glands  are  in  principle,  narrow 
  pouches  of  the  mucous  membranes,  or  of  the  integument, 
  lined  with  a  continuation  of  the  epithelium,  or  of  the 
  epidermis,  the  cells  of  which  produce  the  secretion 
  from  the  blood.  In  the  larger  glands,  the  pouches  are 
  tubular,  greatly  elongated,  and  coiled,  as  in  the  sweat 
  glands,  or  subdivided  and  branched,  making  compound  and 
  racemose  glands,  such  as  the  pancreas.
