B) the thyroid gland, leading to an increase in the blood calcium concentration.
C) the anterior pituitary gland, leading to cessation of gonadal function.

E) the pancreas, leading to a reduction in the blood sugar concentration.

Accepted Answer

The adrenal medulla is responsible for producing and releasing epinephrine (also known as adrenaline), which is a key hormone involved in the fight-or-flight response. This hormone triggers a number of physical responses, including increased heart rate, increased blood pressure, and increased respiration rate to help prepare the body for intense physical activity.
