The part of the brain that monitors various body conditions, and regulates them by sending chemical signals to another organ is the
|
Hypothalamus
|
|
|
The posterior pituitary makes which hormones?
|
NONE! The hormones are STORED in the posterior pituitary are made in the hypothalamus.
Oxytocin, ADH (antidiuretic hormone) |
|
|
The hypothalamus connects to the posterior pituitary via a ?
|
Nerve connection
|
|
|
The hypothalamus connects to the anterior pituitary via a ?
|
Vascular connection
|
|
|
Antidiuertic Hormone (ADH) causes
|
Water retention
|
|
|
If the osmolarity is high, ADH secretion will (Increase, Decrease, Remain Constant)
|
Increase! If you're too salty, you need to ADD H2O (ADH)
|
|
|
A simple word to replace "osmolarity" is
|
Saltiness
|
|
|
In high concentrations, ADH causes ?
|
Constriction of the blood vessels
|
|
|
What are the effects of oxytocin? OXY
|
Uterine contractions, Milk "let down"
NOT production (that's prolactin's job) |
|

Thyroxine, or T3,T4
|
|
|
Three effects of thyroid hormone
|
Increases Basal Metabolic Rate, needed for normal growth, needed for normal maturation of the nervous system
|
|
|
Thyroid hormone is controlled by
|
TSH - Thyroid Stimulating Hormone from the hypothalamic - pituitary system.
|
|
|
TSH levels in someone taking excess thyroid replacement medication (T3, T4) would
|
Be LOW Negative feedback. You have too much T3, T4, why would you ask for more?
|
|
|
TSH levels in someone with low thyroid hormone levels (T3, T4) would be
|
Be high - You need more T3,T4, so you would ASK for it!
|
|
|
Four methods of hormone control are
|
Direct effect, Nerve signal, Hypothalamic - pituitary axis, Renin-angiotensin system
|
|
|
Which hormone requires Iodine for its synthesis? |
Thyroxine, or T3,T4 |
