Which endocrine gland is commonly referred to as the 'master gland' due to its regulatory role over other glands?

A Pituitary gland

B Thyroid gland

C Adrenal gland

D Pineal gland

Solution

Correct Answer: Option A

- The endocrine gland commonly referred to as the "master gland" is the pituitary gland.
- This designation is because the pituitary gland produces hormones that regulate the activity of many other endocrine glands in the body, such as the thyroid, adrenal glands, and reproductive organs.
- Located at the base of the brain, the pituitary gland is controlled by the hypothalamus, which sends signals to stimulate or inhibit hormone release.
- Unlike the thyroid, adrenal, or pineal glands, the pituitary has a central coordinating role, ensuring hormonal balance and integration of bodily functions such as growth, metabolism, and reproduction. Thus, its function is crucial for maintaining overall endocrine system homeostasis.

- In summary, the pituitary gland's role as the primary regulator of other endocrine glands is why it is known as the master gland.
