Pituitary activity is regulated by hormones of the hypothalamus, a brain region. The pituitary gland (or hypophysis cerebri), together with its connections to the hypothalamus, acts as the main endocrine the pituitary gland has a dual origin (ectoderm of the primitive mouth cavity and neuroectoderm of the diencephalon) which reflects related radiopaedia articles.

But it is largely regulated by the hypothalamus.

The pituitary gland is only about 1/3 of an inch in diameter (that's about as large as a pea) and located at the base of the brain. It regulates hormone activity in other endocrine glands and organs. The pituitary gland (or hypophysis cerebri), together with its connections to the hypothalamus, acts as the main endocrine the pituitary gland has a dual origin (ectoderm of the primitive mouth cavity and neuroectoderm of the diencephalon) which reflects related radiopaedia articles.
