Which gland is often referred to as the "master gland" due to its role in hormone production?

Adrenal gland
Thyroid gland
Pituitary gland
Pancreas

The correct answer is: Pituitary gland

The pituitary gland is commonly referred to as the "master gland" because it plays a central role in regulating various hormonal functions in the body. It produces and secretes hormones that influence other glands, such as the thyroid, adrenal glands, and reproductive glands. This gland is crucial for maintaining homeostasis and controlling body processes such as growth, metabolism, and reproduction. Its ability to direct hormone production in these other glands underscores its significance in the endocrine system. The proper functioning of the pituitary gland is essential for overall health, as it orchestrates a wide range of physiological processes through its hormonal signals.
