Exam 25: Endocrine Regulation

Which of the following is not a description of hormone interaction explained in the text?

The many hormones secreted by endocrine tissues can be classified simply as _____ hormones.

Both synergism and permissiveness can increase the effect of a hormone.

Protein hormones, glycoprotein hormones, and peptide hormones all contain amino acids.

Hormones that are antagonistic to each other are able to "fine-tune" the activity of the target cell with great accuracy.

The endocrine system is considered a very efficient system, because virtually every hormone molecule produced finds its target cell receptor.

Most hormones are highly specific in their action.

Aspirin and ibuprofen produce some of their effects by inhibiting PGA synthesis.

Explain how a hormone can act specifically on one type of cell and not on others.

All of the following are nonsteroid hormones except:

Match each term with its explanation or definition. -Increasing the number of receptors on a target cell

Some cases of hormone deficiency can be traced to an obstruction in the duct through which the hormone must pass.

When a small amount of one hormone allows a second hormone to have its full effect, the phenomenon is called:

Prostaglandins are lipid substances derived from cholesterol.

The production of thyroid hormone is stimulated by another hormone from the:

Match each term with its explanation or definition. -Sometimes called a tissue hormone

Match each term with its explanation or definition. -Hormone that targets another endocrine gland

The most widely used method of hormone classification is by location in the body.

With a steroid hormone, the amount of hormone is directly related to the magnitude of the response in the target cell.

Compare and contrast steroid and nonsteroid hormones, and give an example of each.
