Week 10 Flashcards
1
Q
water soluble hormones
A
- amino acid based hormones
- act on specific receptors located in the plasma membrane which then triggers response by the cell
- unable to cross plasma membrane
2
Q
lipid soluble hormones
A
- steroid hormones
- able to cross plasma membrane and enter cell
- acts on receptors located inside the cell to trigger response by cell
3
Q
humoral stimulus
A
- changing levels of a substance within the blood
4
Q
neural stimulus
A
- nerves stimulate the release of hormones by gland
5
Q
hormonal stimulus
A
- hormones released from one gland trigger another gland to release hormones
