In the present study we have established that MC4Rs on neurons in the paraventricular nucleus of the hypothalamus are both necessary and sufficient for MC4R control of feeding and that these neurons are glutamatergic and not GABAergic and do not express the neuropeptides oxytocin, corticotropinreleasing hormone, prodynorphin, or vasopressin.

The paraventricular nucleus (PVN) is an aggregation of neurons in the hypothalamus which produces many hormones. Apomorphine induces selective activation in the nucleus paraventricularis leading to erectogenic signals More than 5,000 men with erectile dysfunction participated in phase II/III clinical trials assessing the safety and efficacy of doses ranging from 2 to 6 mg. Nerve cells of this nucleus form ventricular processes which as clublike endings — “liquor contacting nerve endings” — protrude into the lumen of the 3rd ventricle — The paraventricular nucleus of the turtle, Emys orbicularis, is built up of a proximal neuronal layer situated close to the ependyma, and of a distal group of neurons Synaptic zones can be found between the cell rows.

The paraventricular nucleus of the hypothalamus (PVN) is a complex effector structure that initiates endocrine and autonomic responses to stress It receives inputs from visceral receptors, circulating hormones such as angiotensin II, and limbic circuits and contains neurons that release vasopressin, activate the adrenocortical axis, and activate preganglionic sympathetic or parasympathetic outflows. The term paraventricular nucleus of the hypothalamus refers to a prominent narrow cell group in the anterior hypothalamic region of the hypothalamus Defined classically on the basis of Nissl stain it is bounded rostrally by nuclei of the preoptic area, medially by the preoptic periventricular nucleus, laterally by the preoptic area, anterior hypothalamic area and fornix, ventrally by the dorsomedial nucleus of the hypothalamus and caudally by the dorsal hypothalamic area and/or the. The hypothalamic paraventricular nucleus (PVN) and rostral ventrolateral medulla (RVLM) play a critical role in the generation and maintenance of sympathetic nerve activity The renin–angiotensin system (RAS) in the brain is involved in the pathogenesis of hypertension.

Location The hypothalamic paraventricular nucleus (PVN) is a heterogenous collection of neurons that constitutes one of the principal motor output systems of the hypothalamus It is a bilateral structure located either side of the third ventricle and is an elaboration of the periventricular zone of the hypothalamus. In the medial hypothalamic area, the paraventricular nucleus (PVN) was clearly distinguished as the most effective site for initiating both feeding and drinking with noradrenergic activation in the satiated animal Sites greater than 05 mm rostral, caudal, dorsal, ventral or lateral to this nucleus yielded significantly smaller effects.

Apomorphine SL (Ixense, Uprima) is a new oral medication shown to be effective in the treatment of erectile dysfunction This compound is a dopaminergic agonist with affinity for dopamine receptor sites mostly D (2) within the brain known to be involved in sexual function Apomorphine induces selective activation in the nucleus paraventricularis leading to erectogenic signals.

Background The paraventricular nucleus of the hypothalamus (PVN) has emerged as one of the most important autonomic control centers in the brain, with neurons playing essential roles in controlling stress, metabolism, growth, reproduction, immune and other more traditional autonomic functions (gastrointestinal, renal and cardiovascular).
