Hydrophilic hormones:

1.	activate intracellular receptors
2.	pass through the plasma membrane
3.	bind to membrane receptors to initiate signal transduction pathways
4.	are usually fat-soluble

A paracrine regulator is the one that:
1. is alternatively named a hormone
2. travels through the blood
3. is secreted by the parathyroid gland
4. acts within an organ as a local regulator

Hydrophilic hormones are not characterized by the fact that:
1. They can act through intermediary G proteins.
2. A second messenger (e.g. cAMP) is often involved.
3. They can work by activation of transmembrane receptor proteins.
4. They have a long duration of action (e.g. days).

The proximate cause of a goiter would be:
1. reduced levels of TRH
2. a non-functional thyroid gland
3. elevated levels of thyroid stimulating hormone
4. depressed levels of thyroid stimulating hormone

A decrease in blood glucose is most likely to result in:
1. decreased insulin and glucagon production.
2. increased glucagon production.
3. glycogen being released into the blood.
4. increased glucagon production followed by glucose release from the liver.

When dehydration occurs, the response of the human body would be that:
1. More ADH is secreted.
2. Urine will become less concentrated.
3. Diuretic hormone will be secreted.
4. The urine output will increase.

A person has weight loss, nervousness, tachycardia and intolerance to heat. He may be suffering from:

What term/s would describe adrenaline and noradrenaline?

Cytokines
1. regulate cell division and differentiation in the immune system
2. promote growth and cell division in the nervous system
3. help maintain proper mineral balance in the body
4. help maintain proper water balance in the body

One of the reasons for iodine to be a part of a balanced diet would be:
