ROLE OF HYPOTHALAMUS IN TEMPERATURE REGULATION

ANTERIOR HYPOTHALAMUS:

cooling mechanism

  • sweating
  • vasodialation
  • dec heat production

 

POSTERIOR HYPOTHALAMUS:

  • HEAT GEERSTION
  • SHIVERING
  • VASOCONSTRICTION
  • INC HEAT PRODUCTION BY THYROXINE
  • PILOERECTION

 

 

ChEMICAL THERMOGENESIS

THYROXINE CAUSES INCREASED  BMR AN INC. HEAT PRODUCTION

IN THE END:

students will be able to understand

  • that hypothalamus is playing part both in heat production and dessipation mechanism
  • what is chemical thermogenesis occuring in brown fat
  • heat production by thyroxine
