Its name comes from its location on the ventral surface of the fornix near the interventricular foramina (foramina of Monro), which interconnect the lateral ventricles and the third ventricle. Like all circumventricular … Zobacz więcej As noted above, capillaries in some subregions within the SFO are fenestrated, and thus lack a blood–brain barrier. All circumventricular organs except the subcommissural organ contain fenestrated … Zobacz więcej The subfornical organ is active in many bodily processes, including osmoregulation, cardiovascular regulation, and energy homeostasis. … Zobacz więcej Neurons in the subfornical organ have receptors for many hormones that circulate in the blood but which do not cross the blood–brain barrier, including angiotensin, atrial natriuretic peptide, endothelin and relaxin. The role of the SFO in angiotensin regulation is … Zobacz więcej Hypertension Hypertension, or high blood pressure, is highly affected by the concentration of angiotensin. Injection of angiontensin has actually been … Zobacz więcej Other circumventricular organs participating in systemic regulatory processes are the area postrema and the OVLT. The OVLT and SFO are both interconnected with the nucleus medianus, and together these three structures comprise the … Zobacz więcej The expression of various genes in the subfornical organ have been studied. For example, it was seen that water deprivation in rats led to an upregulation of the Zobacz więcej Feeding Although generally viewed primarily as having roles in homeostasis and cardiovascular … Zobacz więcej

Witryna6 wrz 2024 · The subfornical organ (SFO) is a sensory circumventricular organ located along the anterodorsal wall of the third ventricle. SFO lacks a complete blood-brain barrier (BBB), and thus peripherally-circulating factors can penetrate the SFO parenchyma. These signals are detected by local neurons providing the brain with … WitrynaThe subfornical organ, the organum vasculosum of the terminalis, and the median preoptic nucleus comprise the lamina terminalis. These structures play a role in integrating the control of multiple autonomic systems and so in cardiovascular regulation and the control of fluid balance.
