Nephrogenic diabetes insipidus is a condition where ADH is released by the posterior pituitary but the cells in the kidneys are unable to respond to ADH. This is in contrast to neurogenic diabetes insipidus where the body does not produce enough ADH. When the kidneys are unable to respond to ADH, the urine formation ______ and ADH secretion _______. Which of the following rows correctly completes the sentence above?

Select one:

Urine Formation ADH Secretion Increases Increases in response to decreased water retention

Urine Formation ADH Secretion Decreases Decreases in response to increased water retention

Urine Formation ADH Secretion Decreases Increases in response to increased blood pressure

Melatonin is a hormone made by the pineal gland, a small gland in the brain. Melatonin helps control your sleep and wake cycles. Use the Internet to research how the nervous and endocrine systems control the production and release of melatonin and how melatonin controls your sleep and wake cycles. Evaluate each statement below and select the statement that best describes the pathway.

Select one:

Light on the retina stimulates the hypothalamus to send a signal to the pineal gland to stop producing melatonin, signalling the body to wake up.
