Exam 25: Endocrine Regulation

Endocrine glands are located either in the head or the neck.

Match each chemical classification with a corresponding hormone. -Luteinizing hormone

In comparison with the nervous system, the regulatory effects of the endocrine system are rapidly apparent, but short-lived.

The cAMP system, the inositol triphosphate (IP₃) system, and the mobile-receptor system are second-messenger systems used by nonsteroid hormones.

Examples of steroid hormones are cortisol, aldosterone, and testosterone.

One of the later effects of steroid hormones on the cell could be the:

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

Some nonsteroid hormones attach to cell membrane sodium channels, causing them to open and allowing an influx of sodium into the cell.

One outcome of a nonsteroid hormone would be the synthesis of a specific enzyme.

Match each chemical classification with a corresponding hormone. -Somatostatin

Which of the following is not true of steroid hormones?

Match each term with its explanation or definition. -Usually requires a second messenger to function

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

Thyroid hormones are nonsteroid hormones but act more like steroid hormones when they reach their target cells.

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

The name prostaglandin comes from the prostate gland.

Endocrine glands release their hormones into ducts that eventually empty into the circulatory system.

The specific role of cAMP is to activate kinases.

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

Match each term with its explanation or definition. -A cell with receptors for a specific hormone
