circumventricular organs

(redirected from organum subfornicale)

cir·cum·ven·tric·u·lar or·gans

four small areas in or near the base of the brain that have fenestrated capillaries and are outside the blood-brain barrier. They are the neurohypophysis, the area postrema [TA], the organum vasculosum of the lamina terminalis [TA], and the subfornical organ [TA]. The neurohypophysis is a neurohemal organ. The other three are chemoreceptors: the area postrema triggers vomiting in response to chemical changes in plasma, the organum vasculosum of the lamina terminalis senses osmolality and alters vasopressin secretion, and the subfornal organ initiates drinking in response to angiotensin II.

I am sorry to say anything which may disturb popular delusions on the subject of poetical justice, but this is strictly the truth.
Unhappily, there is no inherent poetical justice in hobbles, and they will sometimes obstinately refuse to inflict their worst consequences on the prime offender, in spite of his loudly expressed wish.
