The pituitary gland, also known as the hypophysis cerebri, is often called the "master gland."
Why is it called the "master gland"?
The pituitary gland earns this title because it controls the functions of many other endocrine glands in the body. It produces several hormones that regulate various bodily processes, influencing everything from growth and metabolism to reproduction and stress response. These hormones act on other glands, stimulating or inhibiting their hormone production. For example, it controls the thyroid gland via Thyroid Stimulating Hormone (TSH), the adrenal glands via Adrenocorticotropic Hormone (ACTH), and the gonads via Follicle-Stimulating Hormone (FSH) and Luteinizing Hormone (LH).
Location and Size:
This pea-sized gland resides in the sella turcica, a bony cavity at the base of the brain, nestled securely within the sphenoid bone. Its small size belies its significant impact on overall bodily function.
