Thermoregulation    by   the
   hypothalamus.
<P>
   In   humans,   the   hypothalamus   functions   as  a  thermostat  for
   thermoregulation.
<P>
<Li> When  body  temperature  increases,  the  thermostat promotes body
cooling by vasodilation, sweating, or <A ClAsS=MIZ Href="../../..//med/evaporative_cooling.html" oNClick="popurlts('../../..//med/evaporative_cooling.html',583,271);txtcolor('hypothalamus1','gray');return false;" Id=hypothalamus1 ClAsS=MIZ>panting.</A>
<Li> When  body temperature decreases, the thermostat activates warming
mechanisms   such   as  vasoconstriction,  erection  of  fur,  and
shivering.
