<span>The pituitary gland is the gland that controls and regulates
all other glands of the body. It is often dubbed as the "master
gland" because the hormones that it secretes control other parts of the
endocrine system. The different endocrine systems are: thyroid, adrenal,
ovaries, and testes glands. Though the pituitary gland is termed as the
"master gland" it still does not perform all the other functions of
the other glands. The pituitary gland is located at the base of the brain.</span>
