____? chemical substances secreted by cells into the
extracellular fluids (into the bloodstream = endo (inside))
Hormones
What does Hormones do to the body
- Regulate the metabolic function of other cells
- Have lag times ranging from seconds to hours
- Tend to have prolonged effects
- Are classified as amino acid-based hormones, or steroids
What can Lipid soluble do to the DNA
It can pernitrate through the DNA
______:insulin vs glucagon, calcitonin and parathyroid
hormone
Antagonistic effect
_____:FSH and Estrogen
Synergistic effect
____:renin converts Angiotensin I to Angiotensin II
Permissive effect
Hormones circulate to all tissues but only activate cells referred to as
Target cell
_______must have specific receptors to which the hormone binds
Target Cell
Where are These receptors may be intracellular or located
the plasma membrane
Target cell activation depends on three factors
- Blood levels of the hormone
- Relative number of receptors on the target cell
- The affinity of those receptors for the hormone
where does the target cells form more receptors in response to the hormone
Up-regulation
Where does the target cells lose receptors in response to the
hormone
Down-regulation
