Question 4

Which hormone is produced by the adrenal medulla and plays a key role in the 'fight-or-flight' response?

Accepted Answer

Epinephrine

Answer

Epinephrine (adrenaline) is secreted by the adrenal medulla and triggers the sympathetic 'fight-or-flight' response.

Question 5

A telehealth patient with type 2 diabetes asks why their kidneys filter glucose into urine. What is the physiological threshold for renal glucose reabsorption?

Accepted Answer

180 mg/dL

Answer

The renal threshold for glucose is approximately 180 mg/dL; above this level, the nephron tubules cannot reabsorb all filtered glucose and it spills into urine.
