acts on target cells only has to knock to enter
What happens to hormones after they react with the target cell
Gets bbroken down by the liver
Why is the hypothalamus in this picture
Its how the nervous system and endocrine system interact… also controls ion levels, hormone and nutrient levels
what is the difference between releasing hormone and stimulating hormone
Releasing- hypothalmus tells pituatary to send out hormone.
Stimulating- pituatary tells what glands to release
What is the main role of the endrocrine System
REMAIN HOMEOSTASIS
What are the 2 main manisfestation of endocrine dysfunction
hypofaction
Hyerfaction
What is imperative for survival in cases of endocrine hypofunction
take a hormone replacement
what is crucial for hyperfunction
take out gland
meds
omit whats causing it… something primary
What is the main regulatory process of the endocrine system
NEGATIVE FEEDBACK
Main causes of gland dysfunction?
Tumors
trauma/sx
Genetic
infarction (bleeding)
Hypothalmus not a glad its just part of the brain T/F
T
Why is the pituitary gland known as the MASTER gland
Regulates many other glands the top of the line

- Trauma
- Genetic Dissorder
what hormones are affected by pituitary disorders?

What is goiter?
Thyroid tries to compensate for lack of iodine by increase in size.
What are 2 main ways to treat thyroid dysfunction
Meds, Surgery
Which part of the adrenal gland does the hypothalamus regulat through hormones
Adrenal Cortex
Which is the main glucorticoid secreted by the adrenal cortex
Cortisol (stress hormone)
What does cortisol do
Gets body ready for another stressful moment
Regulation and utilization of blood glucose\will make soe cells insulin resistent
How might a body have hypocortisolism what is this called
Addisons Disease- autoimmune disease, tumour, ideopathic.
If the adrenal cortex underproduces (hypofunction), what are the effects
skinny
diarhea
How might a body have hypercortisolism what is this called
Cushings syndrome, too much cortisol, medication (hypocortisone)
If the adrenal cortex overproduces (hyperfunction) what are the effects
viscul fat will store unused glucose, limbs and everything else is hungry.
