Exam 25: Endocrine Regulation

All of the following are nonsteroid hormones except:

The endocrine system functions at a much greater speed than the nervous system.

Match each term with its explanation or definition. -cAMP is an example of this

The general effect of hormones is to produce regulatory changes within the target cell.

Responses that result from endocrine feedback loops are called endocrine reflexes.

Match each term with its explanation or definition. -The combination of hormones have a greater effect than the sum of the effects of the two hormones separately

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

Which of the following endocrine glands is located in the neck?

Chemically, steroid hormones are derived from the cholesterol molecule.

Cells make prostaglandins by breaking apart triglyceride molecules.

Compare and contrast how the endocrine and nervous systems function to maintain homeostasis of the internal environment.

Match each term with its explanation or definition. -A small amount of hormone allows another hormone to have its full effect

Both the endocrine and nervous systems exhibit control via regulatory feedback loops.

Steroid hormones tend to generate a rapid response in their target cells.

Which of the following nonsteroid hormones bind to receptors associated with a DNA molecule within the nucleus of the target cell?

Parathyroid hormone reflexively increases secretion of parathyroid hormone in response to an increase in blood calcium levels.

Which of the following is not a characteristic of the endocrine system?

Cells either have receptors for neurotransmitters and respond to the nervous system or have hormone receptors and respond to the endocrine system, but not both.

The control of hormone secretion is usually a positive-feedback loop.

Which of the following is not an amino acid derivative hormone?
