Hormone pathway: Thermoregulation

• The nervous and endocrine systems work together to control body temperature 
• Detection and Initial response: 

  • Temperature change: thermoreceptors detect changes in the body temperature. Information is sent to the hypothalamus
• Nervous System response - Immediate Action 

  • Cold: Hypothalamus trigger shivering and vasoconstriction to converse heat 
  • Heat: hypothalamus initiates sweating and vasodilation to release heat
• Endocrine System response - Hormonal regulation

  • Cold: Hypothalamus stimulates T3 and T4 hormone production to increase metabolism 
  • Stress: Adrenal glands release adrenaline to boost metabolism and heat production
• Thyroid hormones - Long term adjustments

  • Hypothalamus regulates the pituitary gland to influence hormone levels, adjusting metabolism
