- A chemical that is produced in one part of the body but has a response in another
‣
- By blood
‣
‣
‣
- Attaches to protein on cell membrane
- Fast Response

‣
- Goes into cell membrane and into nucleus
- Longer lasting affects

- Thyroid Releasing Hormone (TRH)
- Controls release of Thyroid Stimulating Hormone (TSH)

- Regulates only changes in blood

‣
- When a hormone has the ability to control its own production
‣
- Thyroid
- Hypothalmus recognizes a metabolism needs to be controlled
- Secretes TRH
- TRH tells pituitary gland to secrete TSH
- This tells Thyroid to secrete Thyroxine
- Thyroxine controls cell metabolisms
- When levels of thyroxine in blood are too high it stops production of TRH,TSH and itself
