1
Identify the brain-based endocrine glands mentioned in the problem: the pituitary gland, thyroid gland, parathyroid glands, and adrenal gland.
Recall that the hypothalamus is a part of the brain that controls many autonomic functions and also regulates the endocrine system by communicating with certain glands.
Understand that the pituitary gland is directly connected to the hypothalamus via the infundibulum (pituitary stalk), allowing it to receive signals and release hormones accordingly.
Recognize that the pituitary gland releases hormones that regulate other endocrine glands, such as the thyroid gland, adrenal glands, and gonads, making it the master gland of the endocrine system.
Conclude that among the options, the pituitary gland is the brain-based endocrine gland directly connected to the hypothalamus and responsible for releasing hormones that regulate other endocrine glands.
