Q: non-steroid hormone
Answer:
very commonly amino acid based and is not lipid soluble. It will
actually enter the target cell and act directly on the DNA of the cell. Will also land on
a receptor
on the cell surface, but not enter the cell. In this case a second messenger will carry
out the
work, but the hormone stays outside the cell.
Q: Unction hormones
Answer:
One distinctive feature of hormones whose secretion is regulated
through the hypothalamus and pituitary is that they regulate their own secretion
through
negative feedback inhibition. What this means is that a hormone from a peripheral
gland, for
example, cortisol, binds to its receptor on cells in the hypothalamus and
adenohypophysis, and
has the effect of inhibiting secretion of tropic hormones.
