Question

How does the hypothalamus control both anterior and posterior pituitary functioning?

Answer 1

it controls the functions of ant.pituitary i.e hormone secretion through release stimulating n release inhibiting hormones like controls the secretion of GH from ant.pitu through its GHRH.n it controls the function of post.pituitary through neuronal connections.because the secretions of post.pit r actually through nerve endings so it controls them through neuronal connections.

Answer 2

The two pituitary lobes are the dual origin of the hypothalmus. The posterior pituitary lobe is part of the brain and is a "downgrowth" of hypothalmic tissue and maintains a neural connection with the hypothalmus through a nerve bundle called the hypothalamic-hypophyseal tract. This arises from neurons of the hypothalmus. These cells synthesize two neurohormones and transport them along their axons to the posterior pituitary. Then these neurons "fire" they release the stored hormones into a capillary bed in the posterioir pituitary for distribution throughout the body.  

Answer 3

The hypothalamus is a complex region in the brain of humans, and even small nuclei within the hypothalamus are involved in many different functions. The paraventricular nucleus for instance contains oxytocin and vasopressin (also called antidiuretic hormone) neurons which project to the posterior pituitary, but also contains neurons that regulate ACTH and TSH secretion (which project to the anterior pituitary), gastric reflexes, maternal behavior, blood pressure, feeding, immune responses, and temperature.

The hypothalamus co-ordinates many hormonal and behavioural circadian rhythms, complex patterns of neuroendocrine outputs, complex homeostatic mechanisms, and many important behaviours. The hypothalamus must therefore respond to many different signals, some of which are generated externally and some internally. It is thus richly connected with many parts of the CNS, including the brainstem reticular formation and autonomic zones, the limbic forebrain (particularly the amygdala, septum, diagonal band of Broca, and the olfactory bulbs, and the cerebral cortex).
