hypothalamic-pituitary axis
- hypothalamic-pituitary axis
- the interrelationships between the hypothalamus and the adenohypophysis, both endocrine and neural, including stimulation of the adenohypophysis by neurosecretory neurons, production of releasing and inhibiting hormones in the hypothalamus, reception of the hormones at sites on pituitary acidophils and basophils, production of hormones by acidophils and basophils, and negative feedback mechanisms by which high levels of circulating hormones act on the hypothalamus and adenohypophysis to inhibit secretion of anterior pituitary hormones. Called also hypothalamus-pituitary a.
