  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
 
  Pulse  \Pulse\,  n.  [OE.  pous,  OF  pous,  F.  pouls,  fr  L.  pulsus 
  (sc.  venarum),  the  beating  of  the  pulse,  the  pulse,  from 
  pellere  pulsum  to  beat  strike;  cf  Gr  ?  to  swing,  shake, 
  ?  to  shake.  Cf  {Appeal},  {Compel},  {Impel},  {Push}.] 
  1.  (Physiol.)  The  beating  or  throbbing  of  the  heart  or  blood 
  vessels,  especially  of  the  arteries. 
 
  Note:  In  an  artery  the  pulse  is  due  to  the  expansion  and 
  contraction  of  the  elastic  walls  of  the  artery  by  the 
  action  of  the  heart  upon  the  column  of  blood  in  the 
  arterial  system.  On  the  commencement  of  the  diastole  of 
  the  ventricle,  the  semilunar  valves  are  closed,  and  the 
  aorta  recoils  by  its  elasticity  so  as  to  force  part  of 
  its  contents  into  the  vessels  farther  onwards.  These 
  in  turn,  as  they  already  contain  a  certain  quantity  of 
  blood,  expand,  recover  by  an  elastic  recoil,  and 
  transmit  the  movement  with  diminished  intensity.  Thus  a 
  series  of  movements,  gradually  diminishing  in 
  intensity,  pass  along  the  arterial  system  (see  the  Note 
  under  {Heart}).  For  the  sake  of  convenience,  the  radial 
  artery  at  the  wrist  is  generally  chosen  to  detect  the 
  precise  character  of  the  pulse.  The  pulse  rate  varies 
  with  age,  position,  sex,  stature,  physical  and 
  psychical  influences,  etc 
 
  2.  Any  measured  or  regular  beat  any  short,  quick  motion, 
  regularly  repeated,  as  of  a  medium  in  the  transmission  of 
  light,  sound,  etc.;  oscillation;  vibration;  pulsation; 
  impulse;  beat  movement. 
 
  The  measured  pulse  of  racing  oars.  --Tennyson. 
 
  When  the  ear  receives  any  simple  sound,  it  is  struck 
  by  a  single  pulse  of  the  air,  which  makes  the 
  eardrum  and  the  other  membranous  parts  vibrate 
  according  to  the  nature  and  species  of  the  stroke. 
  --Burke. 
 
  {Pulse  glass},  an  instrument  consisting  to  a  glass  tube  with 
  terminal  bulbs,  and  containing  ether  or  alcohol,  which  the 
  heat  of  the  hand  causes  to  boil;  --  so  called  from  the 
  pulsating  motion  of  the  liquid  when  thus  warmed. 
 
  {Pulse  wave}  (Physiol.),  the  wave  of  increased  pressure 
  started  by  the  ventricular  systole,  radiating  from  the 
  semilunar  valves  over  the  arterial  system,  and  gradually 
  disappearing  in  the  smaller  branches. 
 
  the  pulse  wave  travels  over  the  arterial  system  at 
  the  rate  of  about  29.5  feet  in  a  second  --H.  N. 
  Martin. 
 
  {To  feel  one's  pulse}. 
  a  To  ascertain,  by  the  sense  of  feeling,  the  condition 
  of  the  arterial  pulse. 
  b  Hence  to  sound  one's  opinion;  to  try  to  discover 
  one's  mind.

  {pulsing},  {impulse}] 
  2:  the  rhythmic  contraction  and  expansion  of  the  arteries  with
