Which gland is described as the master gland that regulates other glands and is controlled by the hypothalamus?

• A. Thyroid gland
• B. Adrenal gland
• C. Pituitary gland
• D. Pineal gland

Answer: (C)

The key idea is that the pituitary gland is the central regulator that coordinates the activity of other endocrine glands, with strong control from the hypothalamus. The hypothalamus sends releasing and inhibiting hormones to the pituitary. In the anterior pituitary, these signals trigger the release of hormones like TSH, ACTH, and the gonadotropins (FSH and LH), along with prolactin and growth hormone. Those pituitary hormones then stimulate the thyroid, adrenal cortex, and gonads, shaping their output and activity. The posterior pituitary releases oxytocin and vasopressin, which are produced in the hypothalamus, showing how the hypothalamus and pituitary work together to regulate bodily functions. Because it directs other glands, the pituitary is described as the master gland, and its activity is controlled by the hypothalamus.
