Compare and contrast the functions of the adrenal cortex and the adrenal medulla. In what way are they similar? In what way to the hormones produced differ in terms of their chemical structure and how their levels are controlled?
What will be an ideal response?
For similarities, a student should point out that both parts of the gland function in response to stress by releasing hormones designed to boost physical activity and availability of glucose. For differences, the student should point out that the cortex responds to a pituitary hormone (ACTH) by producing a steroid hormone that primarily raises the availability of blood glucose. The adrenal medulla responds to neural stimulation (by the autonomic nervous system) by producing an amino acid-derived hormone, epinephrine, that raises heart and breathing rate and blood pressure, reduces blood supply to the gut.

Nerve impulses travel along neurons by the opening of channels that allow sodium ions to flow inward, followed by an outward flow of potassium ions
In order to ensure that the impulse may be produced at any time, sodium is actively transported out of the cell and potassium is transported into the cell by the sodium/potassium pump. Which of the following types of work is performed by the sodium/potassium pump? A) mechanical B) electrical C) concentration D) synthetic E) bioluminescent
