Provide one example for each way endocrine glands are stimulated to release their hormones.

Explain what mechanism of hormone action is occurring in this image. How does it work? Give an example of a hormone that uses this mechanism.

What six hormones primarily affect growth?

Describe the chemical nature of hormones.

Define hormone.

What four conditions cause the release of erythropoietin?

In what ways can a hormone modify the activities of its target cells?

Which type of hormone receptor—plasma membrane bound or intracellular—would be expected to provide the most long-lived response to hormone binding and why?

In Type 2 diabetes, insulin levels are frequently normal, yet the target cells are less sensitive to the effects of insulin. This suggests that the target cells (a) are impermeable to insulin, (b) may lack enough insulin receptors, (c) cannot convert insulin to an active form, (d) have adequate internal supplies of glucose, (e) both b and c.
