Q

How and where does the hypothalamus send messages?

A
  • stimulates the autonomic nerves by releasing hormones from the pituitary gland to the peripehral organs
  • link between endocrine and nervous sytems
  • regulates HR, BP, temp, fluid and electrolytes, appetite, body weight, glandular secretions in stomach and intestines, sleep

Q

Negative Feedback System

A
  • Hypothalamus senses a need for particular hormone
  • Secretes releasing factor directly into anterior pituitary
  • Response = anterior pituitary secretes hormone, and this stimulates the gland
  • Hypothalamus will sense increases for particular hormone and send messages to anterior pituitary to stop producing the hormone

Ex: blood calcium
* parathyroid gland secretes PTH, which regulates Ca in the blood
* if Ca decreases, PT glands sense decrease and secrete more PTH which stim Ca release from bones and increases Ca uptake into blood and vise versa
