What are the two parts of the pituitary gland?
The pituitary gland has two main parts: neurohypophysis and adenohypophysis. The neurohypophysis is an actual downgrowth of the diencephalon directly connected to the hypothalamus. Both parts include the infundibulum. The neurohypophysis incorporates the stem of the infundibulum, which is a continuation of the median eminence of the tuber cinereum. It also contains the posterior (neural) lobe. The adenohypophysis can be separated into the pars intermedia (the boundary between the two pituitary lobes) and the pars anterior (anterior lobe), both forming a part of the adenohypophysis. The adenohypophysis also contains the pars tuberalis, a vascularized sheath surrounding the stem of the infundibulum.
How does the hypothalamus control the endocrine system?
The hypothalamus controls the endocrine system via several pathways. These include direct projections to the posterior pituitary (neurohypophysis), and indirect control over the anterior pituitary (adenohypophysis) via projections to the median eminence and via the autonomic nervous system. The hypothalamus carries out its control by producing releasing or inhibiting hormones, known as neurohormones. Releasing hormones stimulate the production of hormones in the pituitary gland, whilst inhibiting hormones inhibit it.
