hypothalamus and its target organs; and
The hypothalamus-pituitary complex is found in the brain's diencephalon. The infundibulum, a system that includes vasculature and nerve axons, binds the hypothalamus and pituitary gland. The pituitary gland is split into two halves, each of which has a separate embryonic origin. The axon terminals of hypothalamic neurons are located in the posterior lobe. It stores and releases two hypothalamic hormones into the bloodstream: oxytocin and antidiuretic hormone (ADH). The anterior lobe develops and secretes six hormones and is linked to the hypothalamus by vasculature in the infundibulum.
By means of the pituitary gland, the hypothalamus binds the nervous and endocrine systems. Its role is to secrete releasing hormones and inhibiting hormones that promote or suppress hormone development in the anterior pituitary, as their names indicate.
The hypothalamus, on the other hand, regulates their secretion by releasing and inhibiting hormones.
