Quizplus · Accepted Answer

While the pituitary gland is commonly referred to as the "master gland" because it produces and releases many hormones that regulate various bodily functions, it is important to note that it is still under the control of the brain.

Therefore, while the term "master gland" implies that it controls all other glands and structures in the body, it is not entirely accurate.
