Exocrine: ducted (Sweat, saliva). Endocrine: ductless (Secrete hormones into ISF or blood)
1 of 12
Is the endocrine system fast or slow acting, and short lived or prolonged?
Slow and prolonged.
2 of 12
What are the three types of hormone transfer?
Circulating (through the blood), Paracrine (acts on neighbouring cells), Autocrine (Acts on same cell).
3 of 12
What are the two types of hormone solubility?
Water soluble and Lipid soluble.
4 of 12
How do lipid soluble hormones travel around the body?
Using transport proteins.
5 of 12
What are the three classes of lipid soluble proteins?
Steroids, Thyroid hormones and Nitric oxide.
6 of 12
What are the three classes of water soluble proteins?
Amines (decarboxylated amino acids, always has amine group), Peptide & proteins (chains of amino acids) and Eicosanoids (derived from fatty acid)
7 of 12
How do lipid soluble hormones activate their receptors?
As they are fat soluble, they cross the cell membrane and alter gene expression of a protein, this protein then produces the effect.
8 of 12
How do water soluble hormones activate their receptors?
They bind to receptors on the cell membrane which activates a secondary messenger, this amplifies the original small signal and leads to protein production, causing a physiological response.
9 of 12
What is a Permissive effect?
When a second hormone strengthens the effects of the first
10 of 12
What is a Synergistic effect?
Two hormones acting together for greater effect
11 of 12
What is an Antagonistic effect?
Two hormones with opposite effects.
